The MS8104160 is a single-chip 4Mb FIFO functionally composed of two OKI 2Mb FIFO (First-In First-Out) memories which were designed for 256k 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 MS8104160, functionally compatible with Oki's 2Mb FIFO memory (MSM518222A), can be used as a x16 configuration FIFO. The MS8104160 is a field memory for wide or low end use in general commodity TVs and VTRs exclusively and is not designed for high end use in professional graphics systems, which require long term picture storage, data storage, medical use and other storage systems.
