Abstract

A Static Random Access Memory (SRAM) includes at least two memory cells sharing a read bit line (RBL) and a write bit line (WBL). Each memory cell is coupled to a respective read word line (RWL) and a respective write word line (WWL). A write tracking control circuit is coupled to the memory cells for determining a write time of the memory cells. The write tracking control circuit is capable of receiving an input voltage and providing an output voltage. The respective RWL and the respective WWL of each memory cell are asserted during a write tracking operation.
