Abstract
A write operation is performed by using a sequentially-incremented write address upon a first-in first-out memory device, and a read operation is performed by using a sequentially-incremented read address upon the first-in first-out memory device. The write address is cleared by a write reset signal, and the read address is cleared by a read reset signal. A delay circuit is provided to coincide an effective timing of the write reset signal in the memory cell array with that of the read reset signal in the memory cell array.
