Abstract
A domino SRAM is provided with active pull-up PFET devices that overwhelm 'slow to write but very fast to read' cells and allow the cells to recover from timing mismatch situations. This approach allows the traditional 'bit select' clamp to actively control the “local select” through “wired-or” PFET pull-up transistors. Separate read and write global “bit line” pairs allow the read and write performance to be optimized independently.
