Memory chip and layout design for manufacturing same

摘要

An embedded synchronous random access memory (SRAM) chip, includes a first single-port (SP) SRAM macro and a second SP macro. The first macro includes a first periphery circuit, and a plurality of first SRAM cells. The second macro includes a second periphery circuit, and a plurality of second SRAM cells. Further, each cell of the plurality of first SRAM cells is electrically connected to a write-assist circuitry, wherein the write assist circuitry is configured to assist the write cycle capability of each cell of the plurality of first SRAM cells. Further, each cell of the plurality of second SRAM cells do not include write assist circuitry.
