GENERAL DESCRIPTION
The MS81V04166 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 MS81V04166 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 MS81V04166 provides high speed FIFO (First-in First-out) operation without external refreshing: MS81V04166 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 for any duration as long as the power is on. Internal conflicts of memory access and refreshing operations are prevented by special arbitration logic.
