摘要:
A semiconductor chip has an SRAM (static random access memory). The SRAM includes a data dependent write assist circuit which, on writes, reduces a supply voltage on one of a cross coupled inverter pair in an SRAM cell, thereby making it easier to overcome the one of the cross coupled inverters.
