A FIFO memory eliminates the delay associated with selecting memory locations during a read and write operation and prevents data intended to be saved from changing during the write operation. The FIFO memory includes a shift register having a plurality of memory locations, data input and data output terminals coupled to the memory, a first memory location coupled to the data output terminal that is immediately output enabled in response to a read operation, and a single pointer arrangement coupled to the memory locations for selectively saving data contents in successive memory locations coincidentally with the occurrence of successive write operations.
