Implementing local evaluation of domino read sram with enhanced sram cell stability

Abstract

A method and circuit for implementing domino static random access memory (SRAM) local evaluation with enhanced SRAM cell stability, and a design structure on which the subject circuit resides are provided. A SRAM local evaluation circuit enabling a read and write operations of an associated SRAM cell group includes true and complement bitlines, a single write data propagation input, a precharge signal, and a precharge write signal. A passgate device is connected between the complement bitline and the write data propagation input. A transistor stack is connected in series with the precharge device between the true bitline and ground. The precharge write signal disables the passgate device connected between the complement bitline and the write data propagation input during a read operation. During write operations, the precharge write signal enables the passgate device connected between the complement bitline and the write data propagation input and activates the transistor stack.
