MS8104166A

OKI Semiconductor MS8104166A Dual FIFO (262,214 Words × 8 Bits) × 2 FEDS8104166A-01 This version: Nov.,21, 2002 GENERAL DESCRIPTION The MS8104166A is a single-chip 4Mb FIFO functionally composed of two Oki’s 2Mb FIFO (First-In First-Out) memories which were designed for 256k × 8-bit high-speed asynchronous read/write operation. www.DataSheet4U.com The read clock of each of the 2Mb FIFO memories is connected in common, and the clocks are provided independently of each of the FIFO memories. The MS8104166A functionally compatible with Oki’s 2Mb FIFO memory (MSM518222A), can be used as a ×16 configuration FIFO. The MS8104166A 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. The MS8104166A provides independent control clocks to support asynchronous read and write operations. Different clock rates are also supported, which allow alternate data rates between write and read data streams. The MS8104166A provides high speed FIFO (First-in First-out) operation without external refreshing: MS8104166A refreshes its DRAM storage cells automatically, so that it appears fully static to the users. Moreover, fully static type memory cells and decoders for serial access enable the refresh free serial access operation, so that serial read and/or write control clock can be halted high or low fo...
