ABSTRACT:
In a first-in first-out memory circuit using a standard cell library memory, a memory block includes N number of memories (N>1). A read pointer designates read addresses of the N number of memories. A write pointer designates write addresses of the N number of memories. A memory controller selects one from the N number of memories based on the read/write addresses, generates n number of read/write clock signals by demultiplying a clock signal by n (n=N, n>1) and sends the n number of read/write clock signals having a 1
cycle difference to the N number of memories thereby inputting/outputting data.
