Abstract:
A static random access memory (SRAM) includes fast SRAM bit cells and fast multiplexer circuits that are formed in a first row of fast cells in a hybrid standard cell architecture. Slow SRAM bit cells and slow multiplexer circuits are formed in a second row of slow cells. The slow multiplexer circuits provide a column output for the fast SRAM bit cells and the fast multiplexer circuits provide a column output for the slow SRAM bit cells. Thus, one SRAM column has fast bit cells and slow multiplexer stages while the adjacent SRAM column has slow bit cells and fast multiplexer stages to thereby provide an improved performance balance when reading the SRAM.
