ABSTRACT:
A static random access memory (SRAM) can include an array of memory cells, wherein each memory cell is coupled to one of a plurality of sense amplifiers through a bitline. The SRAM also can include replica bitline circuitry including a replica bitline coupled to a replica bitline amplifier. The replica bitline amplifier can provide a strobe signal to the plurality of sense amplifiers, wherein the replica bitline amplifier includes a feedback path. An SRAM also may include a write replica circuit generating a signal when data has been written to the write replica circuit. A wordline of the memory array can be turned off responsive to the signal.
