Abstract
A dual-port Static Random Access Memory (SRAM) cell is disclosed that includes a storage element that is operable to store a data bit and a complement data bit. The dual-port SRAM cell further includes read access circuitry dedicated exclusively to a read operation and write access circuitry dedicated exclusively to a write operation. The read operation and the write operation are performed in a staggered manner. With the read operation performed exclusive on one port and the write operation performed exclusively on the other port of the SRAM cell, smaller transistors can be used to reduce the size of the SRAM cell.
