Abstract

 

A method for improving writability of an SRAM cell is disclosed. In one aspect, the method includes applying a first voltage higher than the global ground voltage and a third voltage higher than the global supply voltage to the ground supply nodes of the invertors of the SRAM cell, pre-charging one of the complementary bitlines to the global ground voltage, and applying a second voltage higher than the global supply voltage to the access transistors during a write operation to the SRAM cell.
