can be very quickly pulled down sufficiently to turn the transistor 76 on because the nmos transistor 84 need not drive the word line wl as a result transistor 76 can very quickly turn off the pmos transistors 78 80 and quickly turn on the nmos transistor 82 the faster switching times of the transistors 80 82 has not only the benefit of providing faster performance but since the period of time that both transistors 80 82 are on may be reduced power consumption may be also reduced with further reference to fig3 a precharge command is subsequently provided as shown in fig3 b a short time later the group phase signal gph transitions low to reset the latch 74 and turn on the nmos transistors 82 84 resetting the latch also turns off the pmos transistor 80 to allow the word line wl to be driven low by the transistor 82 however before the gph signal transitions low the power supply switch 92 switches the voltage v 2 from v ccp to v cc as shown in fig3 h thereby reducing the voltage of the word line wl as a result when the nmos transistor 82 turns on the source to drain voltage of the transistor 82 is relatively low thereby avoiding chc damage to the transistor 82 the word line wl thus transitions low in two stages first from.
