Patent ID: 7746717

Claim:
A static random access memory comprising: an array of memory cells, wherein each memory cell of the array of memory cells is coupled to a sense amplifier through a bitline; and replica bitline circuitry comprising a replica bitline coupled to a replica bitline amplifier, wherein the replica bitline amplifier provides a strobe signal to the plurality of sense amplifiers, wherein the replica bitline amplifier comprises a feedback path, wherein an input of the replica bitline amplifier is coupled to the replica bitline and an output of the replica bitline amplifier is coupled to the plurality of sense amplifiers, wherein the feedback path feeds a signal back to the input of the replica bitline amplifier, and wherein the replica bitline amplifier comprises: a first amplification stage comprising an input coupled to the replica bitline; and a second amplification stage, wherein an input of the second amplification stage is coupled to an output of the first amplification stage and an output of the second amplification stage is coupled to the plurality of sense amplifiers, wherein the feedback path is a positive feedback path that couples the output of the first amplification stage to the input of the first amplification stage.
