semiconductor material . as can be seen , the required operation voltage v r ( shown as curve 102 ) begins at a minimum voltage v 0 . as the device ages , however , additional voltage is required to compensate for the aging semiconductor material in the electronic device , and approaches a maximum voltage ( v max ) at the end of the operational life of the device . for instance , if the device is designed to have an operational life of 10 years , then v r would be v max after 10 years of operation . this voltage is represented by curve 104 in fig1 . one method to combat semiconductor aging is to overcorrect ( at least initially ) by setting the operational voltage ( v op ) for devices to the maximum voltage ( v maxx ), even at the beginning of use . the problem with this method is that there is a significant period of time during the operational life of an electronic device when the operational voltage of the device is set to be much higher than required to combat the effects of the aging semiconductor . this results in increased power consumption compared to what is necessary to run the electronic device , which can result in reduced battery life , increased cost of operation , and consumer dissatisfaction . fig2 is a functional block diagram of an electronic semiconductor device 200 according to embodiments of the present disclosure . the semiconductor device 200 includes a variable power supply 202 and an operational component 204 . the operational component 204 can comprise a number of different components used for performing the functions the device is intended to perform . furthermore , the operational component 204 can be manufactured as a single semiconducting element ( i . e ., a system on chip or asic ) or be comprised of a number of separate semiconductor devices . herein , semiconductor devices are devices that are produced , at least in part , out of a semiconductor material , such as silicon , gallium arsenide ( gaas ), germanium , etc , and have electronic functionality , as will be understood by those skilled in the art . it should be noted , however , that embodiments of the invention can cover the end - to - end aging of the whole product and not just the semiconducting components . for instance , embodiments of the invention could be used to cover the aging of the voltage regulator , the aging of printed circuit board interconnects , the aging of decoupling capacitors on the voltage supply , and the aging of other electronic and / or semiconductor components as will be understood by those skilled in the arts . the operational component 204 may include a controller 212 , a memory 206 , and input / output component 208 , and a tx / rx communications component 210 . each of the various operational components 206 , 208 , 210 , and 212 is powered by the variable power supply 202 via power connections 222 a , 222 b , 222 c , and 222 d ( generically referred to as power connections 222 ). additionally , the controller 212 is connected to variable power supply 202 via control connection 224 . according to embodiments , the variable power supply 202 can be configured to supply each of components 206 , 208 , 210 , and 212 of the operational component with the same operational voltage or with different operational voltages . additionally , the variable power supply may comprise a plurality of power supplies , each of which may be variable or not variable . according to embodiments of the disclosure , the controller 212 is configured to communicate with the variable power supply via control connection 224 and to provide instructions that cause the variable power supply to set one or more output supply voltage levels through connections 222 . the memory 206 can comprise any sort of computer readable memory such as a magnetic disk drive , an optical drive , flash memory , eeprom , etc . the memory 206 preferably is configured to store program memory for various applications of the electronic device 200 . the tx / rx component 210 can be configured to connect to and communicate with a wireless or wired communications network through any of a variety of well - known means . the i / o component 208 provides a user interface and can include keyboards , touch pads , touch screens , led displays , etc . fig3 illustrates a method 300 of mitigating the effects of aging semiconductor material according to embodiments of the disclosure . according to the method , the electronic device 200 is initialized at step 302 . the device can be initialized by setting the operational voltage supplied by the variable power supply 202 to an initial voltage . according to some embodiments , this initial voltage can be the maximum voltage ( v max ) required to compensate for semiconductor aging over the course of the operational life of the device . at step 304 , the method determines whether the device can detect the current time . according to some embodiments , this is done by verifying a connection to a network capable of providing the current time . however , according to other embodiments , the device determines that it can detect the correct time by verifying an internal clock functionality . according to some embodiments , the electronic device can use the controller &# 39 ; s clock to perform this step , however , it is also envisioned that a second clock external to the controller could be provided for this purpose . if the current time cannot be detected , then the operating voltage is set to a maximum operating voltage v max at step 306 and the method is complete . according to some embodiments , v max is the same as the maximum voltage required to compensate for semiconductor aging over the course of the operational life of the electronic device . in embodiments where the initial voltage was already set to this value at step 302 , no change in operational voltage occurs . if at step 304 , it is determined that the current time can be detected , then the current time is determined and an appropriate operating voltage is determined based on the current time , at step 308 . according to embodiments of the present disclosure , the appropriate operating voltage is determined by first determining the amount of elapsed time since an initial start - up time , and referencing a look - up table or some other appropriate data structure to retrieve the appropriate operating voltage from memory 206 according to the elapsed time . according to embodiments of the invention , the initial start - up time ( including date ) can also be an in - service date or a date of manufacture . additionally , if start - up time may be stored in a non - volatile storage element such as a readable fuse array , one - time programmable memory , prom , flash memory , or a hard drive . finally , the controller 212 can command the variable power supply 202 to set the appropriate operating voltage at step 310 . as discussed above , the method 300 determines the appropriate operating voltage based on elapsed time since an initial startup . the schedule of appropriate operating voltages based on elapsed time can be based , for instance , on models of how the semiconducting materials in the electronic device age . table 1 demonstrates an example schedule for varying the operating voltage assuming , for the sake of illustration , that v 0 is 1 volt and v max is 2 volts . as shown in table 1 , in the initial week of operation , the device may not require any voltage margin to ensure normal operation . v 0 is the minimum operating voltage of the device without accounting for the aging of the semiconductor device and v max is the maximum voltage required during the projected lifetime of the device . however , the operational voltage can be increased from v 0 by a voltage margin ( i . e ., the difference between v max and v 0 ). accordingly , during the first week , the appropriate operating voltage is 1 . 0 v . after the first week up to the end of the first year , the appropriate operating voltage to be supplied by the power supply 202 is 1 . 33 v . after the first year , but before the second year , the appropriate operating voltage is 1 . 5 v . finally , after the second year , the appropriate operating voltage power supply is 2 v , which , in this illustrative case , is the maximum voltage that will ever be required in order to compensate for the aging of the semiconducting components of the device over the course of its planned operational life . fig4 illustrates the way the operational voltage ( v op ) 404 can be made to vary with time according to embodiments of the disclosure . as shown in fig4 at time t 0 , the initial operational voltage is set to v 1 , where v 1 is some voltage greater than the minimum required operational voltage v 0 that is required by the device without semiconductor aging . as shown in fig4 , the required operational voltage ( minimum voltage plus the required voltage margin ) 402 increases with time . accordingly , at time t 1 , the operational voltage ( v op ) 404 increases to v 2 . a similar increase in v op is made at time t 2 to v 3 . in this way , the operational always remains above the required operational voltage 402 . according to some embodiments , various components of the electronic device 200 may require increases in the their individual v 0 ) at different rates in order to compensate for different aging timelines for their semiconductor materials . for instance , assume controller 212 ages more quickly than memory 206 . one way to compensate would be to simply increase the operational voltage for the entire operational component 204 at the rate required for the more quickly aging component . however , it would be more efficient to only increase the operational voltage for each component as needed according to its individual aging profile . the method for this kind of compensation is illustrated in fig5 . fig5 illustrates a method 500 of compensating for aging semiconductor material according to embodiments of the disclosure . method 500 differs from the previously described method 300 in that it provides two different operational voltages to two different portions of the operational component of the electronic device . according to method 500 , the device is first initialized at step 502 . according to embodiments , this initialization can set a first operational voltage to a first initial voltage and a second operational voltage to a second initial voltage . the first and second initial voltages can be the same or different . for instance , both could be set to the maximum voltage required to counteract the effects of the aging semiconducting material , or only one set to the maximum voltage and the other set to a lower voltage . at step 504 , it is determined whether the device can detect the current time . according to some embodiments , the device determines that it can detect the current time by verifying access to a network that broadcasts current time information . however , as discussed above , the device 200 can also determine that it can detect the correct time by verifying an internal clock functionality . according to some embodiments , the electronic device can use the controller &# 39 ; s clock to perform this step , however , it is also envisioned that a second clock external to the controller could be provided for this purpose . if the device is unable to detect the current time , then it sets both the first and second operating voltages to the maximum voltage required to combat the effects of aging during the operational life of the of the device . if , at step 504 , the current time can be detected , then an appropriate first operating voltage is determined at step 508 based on the elapsed time since an initial time . similarly , an appropriate second operating voltage is determined at step 510 based on the elapsed time since an initial time . at step 512 , the first and second operating voltages are set to the appropriate levels determined at steps 508 and 510 , respectively . table 2 provides an illustrative example of how the schedule of the two operating voltages might increase with time . assume , for instance , that most of the components of the electronic device 200 require increased voltage at the first required voltage schedule , but that the controller 212 requires an increased voltage according to the second required voltage schedule . again , the values of v 0 and v max are 1 and 2 volts for this example . as shown in table 2 , during an initial period t 0 ( e . g ., up to the first week of operation ), the first operational voltage requires no additional offset and the second required voltage requires an additional voltage margin of 50 % ( i . e ., 50 % of ( v max - v 0 )). accordingly , the controller 212 can send a signal to the variable supply 202 to cause it to provide a first operational voltage of 1 v to the memory component 206 , i / o component 208 , and tx / rx component 210 . the second operational voltage of 1 . 5 v can then be supplied to controller 212 at this point . during a second period of time t 1 ( i . e ., after the first week but before the first year has elapsed ), the first required voltage must be increased to provide a 33 % voltage margin , however the second required voltage does not need to change . accordingly , the power supply can produce first and second operational voltages of 1 . 33 v and 1 . 5 v , respectively . during a third time period t 2 ( i . e ., from one to two years ), the first required voltage does not need to change , but the second required voltage needs to be changed to provide an 80 % voltage margin . accordingly , the power supply can produce first and second operational voltages of 1 . 33 v and 1 . 8 v , respectively . during the fourth time period t 3 ( i . e ., after 2 years have elapsed ), the first required voltage increased by a 50 % voltage margin while the second required voltage remains unchanged . accordingly , the power supply can produce first and second operational voltages of 1 . 5 v and 1 . 8 v , respectively . fig6 illustrates the way that the first operational voltage 604 and the second operational voltage 606 can vary so that they are always greater than the required voltage 602 . as shown in fig6 , at time t 0 , first operational voltage is set to v 1 and second operational voltage 606 is set to v 3 . at time t 1 , in order to remain higher than required voltage 602 , first operational voltage 604 is increased to v 2 . at time t 2 , second operational voltage 606 is increased to v 4 . at time t 3 , the first operational voltage is increased to v 3 . thus , as can be seen from fig6 , the first and second operational voltages can increase at different rates and provide different voltage margins . while the disclosure has been described with respect to first and second operational voltages and an operational component having two portions , it is envisioned that the operational component could be divided into any number of portions in order to optimize power consumption . additionally , according to some embodiments , the power supply may actually comprise several individual power supplies which may or may not be variable themselves . according to embodiments of the present disclosure , the initial time is a time that has been stored in the memory of device . the initial time is generally indicative of a time when the device entered service . for instance , the initial time could be set during manufacture or during initial testing . similarly , the initial time could be set during the first time the electronic device is initialized . various aspects of the
