    摘要: A static random access memory (SRAM) can include a plurality of columns forming a memory array, wherein each column comprises a plurality of memory cells coupled to bitlines and wordlines, and a write replica circuit generating a signal when data has been written to the write replica circuit. A wordline of the memory array is turned off responsive to the signal. The write replica circuit can include an additional column comprising at least one dual port dummy memory cell, and write detection circuitry coupled to the dual port dummy memory cell detecting when data has been written to the dual port dummy memory cell and responsively generating the signal. The signal generated by the write detection circuitry indicates a successful write operation to the dual port dummy memory cell.

    摘要: 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.
