DESCRIPTION:
memory devices commonly known as FIFOs (First-In/First-
Out). Data can be written into and read from the memory at
independent rates. The order of information stored and ex-
tracted does not change, but the rate of data entering the FIFO
might be different than the rate leaving the FIFO. Unlike a
Static RAM, no address information is required because the
read and write pointers advance sequentially. The IDT72021/
031/041s can perform asynchronous and simultaneous read
and write operations. There are four status flags, (
