GENERAL DESCRIPTION
The MS81V04160A is a single-chip 4Mb FIFO functionally composed of two OKI 2Mb FIFO (First-In First-Out) memories which were designed for 262,214 x 8-bit high-speed asynchronous read/write operation.
The read clocks and the write clocks of each of the 2Mb FIFO memories are connected in common. The
MS81V04160A, functionally compatible with Oki's 2Mb FIFO memory (MSM51V8222A), can be used as a x16 configuration FIFO.
