Implementing Local Evaluation of Domino Read SRAM With Enhanced SRAM Cell Stability and Enhanced Area Usage
摘要:
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, true and complement write data propagation inputs, a precharge signal, and a precharge write signal. A respective precharge device is connected between a voltage supply VDD and the true bitline and the complement bitline. A first passgate device is connected between the complement bitline and the true write data propagation input. A second passgate device is connected between the true bitline and the complement write data propagation input. The precharge write signal disables the passgate devices during a read operation. During write operations, the precharge write signal enables the passgate devices.
