Abstract:
A memory array has word lines and bit lines. A row decoder is operable to decode a row address and select a corresponding word line. A read-write clock generator is operable to generate a hold clock signal. An address clock generator receives a read address, a write address, a dual port mode control signal, a read chip select signal, and a write chip select signal. When operating in dual port mode, and when operating in a read mode, the address clock generator applies a read delay to the read address and outputs the read address, as delayed, to the row pre-decoder as the address in response to the hold clock signal.
