What is Static random-access memory?
'''Static random-access memory''' ('''SRAM''') is a type of [[RAM]] that keeps [[data]] that is fed to it without having to be refreshed over and over again. Both [[DRAM]] and SRAM store information in [[binary]] by using very small [[electronic component]]s. Both are [[Non-volatile random-access memory|volatile]] (need [[electric current]] flowing to make the negative and positively [[electric charge|charged]] components stay that way). One difference is that SRAM are also used for specific applications within the [[personal computer|PC]], where their good points outweigh their bad points compared to [[DRAM]]. Like other [[semiconductor]] chips, SRAM chips are made by [[photolithography]]. For SRAM, each bit is composed of between four and six [[transistor]]s, forming a [[Flip-flop (electronics)|flip-flop]] to hold information. This complexity is what makes SRAM bigger and more expensive than [[DRAM]]. In [[DRAM]] each bit has only one transistor plus a [[capacitor]] acting like a miniature [[rechargeable battery]]). ==Advantages== * SRAM does not need to be refreshed. * Changing Static RAM is faster than [[DRAM]]. ==Disadvantages== * SRAM is more expensive than [[DRAM]]. * SRAMs take up more space and electricity. == Other websites == * [http://www.intel.com/pressroom/archive/releases/20070918corp_a.htm?iid=tech_arch_32nm+body_pressrelease Uses of SRAM by Intel Corp.] {{Tech-stub}} [[Category:Computer memory]]
