ABSTRACT:
A semiconductor memory has an output data latch circuit controlled in response to a clock signal shifted by a half period from a control clock input to n one-bit shift register stages. The memory device includes a plurality of read data latch circuits, as well as a plurality of write or address data latch circuits, coupled to the n one-bit shift register stages and to a plurality of selector or multiplexor circuits. A noise filter is inserted in a clock input supply path to the n one-bit shift register stages but is not inserted in a clock input supply path to the output data latch circuit.
