Abstract
A high bandwidth register file circuit that significantly reduces the shared local read bitline RC delay to enable ultra-high performance PRFs with high port counts. In one example, the register file circuit includes read stack nfets in a multiplexer circuit instead of the memory cell causing the local read bitline RC to be independent of the number of read and write ports of the memory cell.
