Abstract
Techniques are provided for reducing power consumption in memory cells. A static (SRAM) memory cell includes two cross coupled inverters. One or more transistors are coupled between the inverters and the power supply voltages. The transistors are turned OFF for a period of time during a memory state transition to block current flow between the high power supply voltage and the low power supply voltage to reduce power consumption.
