DESCRIPTION
The M66257FP is a high-speed line memory with a FIFO (First In First Out) structure of 5120-word × 8-bit double configuration which uses high-performance silicon gate CMOS process technology.
It allows simultaneous output of 1-line delay data and 2-line delay data, and is most suitable for data correction over multiple lines.
It has separate clock, enable and reset signals for write and read, and is most suitable as a buffer memory between devices with different data processing throughput.

FEATURES
• Memory configuration of 5120 words × 8 bits × 2 (dynamic memory)
• High-speed cycle ............................................. 25ns (Min.)
• High-speed access ......................................... 18ns (Max.)
• Output hold ........................................................ 3ns (Min.)
• Fully independent, asynchronous write and read operations
• Output .................................................................... 3 states
• Q00 to Q07 ........................................................ 1-line delay
• Q10 to Q17 ........................................................ 2-line delay

APPLICATION
   Digital photocopiers, high-speed facsimile, laser beam printers.
