ABSTRACT:
An FIFO memory device which is used for digital communication devices and the like comprises a plurality of D-flip flops cascade-connected with each other for storing data; selectors connected between the D-flip flops for selecting an input data or a data to be stored which is outputted from the D-flip flop on the previous stage; and control circuits responsive to a clock signal, a write signal and a read signal for controlling the storing operation of the D-flip flops and the selection operation of the selectors. The control circuit stores a signal representative of presence or absence of data stored in the D-flip flops and performs control in such a manner that an input data is transferred to the D-flip flop on the final stage in which no data has been written for writing the data therein in response to a write signal and that data on respective D-flip flops are simultaneously shifted to the D-flip flop on the subsequent stage on every clock in response to a read signal.
