Abstract
A multi-port (e.g., two port) CMOS static random access memory (SRAM) with a local clock driver generating clocks for boundary latches. Local clocks select between address inputs clocked into the boundary latches. A read clock selects and latches a read address in the boundary latches. A second clock latches write addresses and, when appropriate, test data addresses.
