M5M4257S-20 - 256K-Bit DRAM

Download the M5M4257S-20 datasheet PDF. This datasheet also covers the M5M4257S-12 variant, as both devices belong to the same 256k-bit dram family and are provided as variant models within a single manufacturer datasheet.

Description

This is a family of 262 l44-word by l-bit dynamic RAMs, fabricated with the high performance N-channel silicon gate MOS process, and is ideal for large-capacity memory systems where high speed, low power dissipation, and low costs are essential.

MITSUBISHI LSls MSM42S7S·12, -15, -20 262 i44-BIT (262 i44-WORD BY i-BIT) DYNAMIC RAM DESCRIPTION This is a family of 262 l44-word by l-bit dynamic RAMs, fabricated with the high performance N-channel silicon gate MOS process, and is ideal for large-capacity memory systems where high speed, low power dissipation, and low costs are essential. The use of double-layer polysilicon process combined with silicide technology and a singletransistor dynamic storage cell provide high circuit density at reduced costs, and the use of dynamic circuitry including sense amplifiers assures low power dissipation. Multiplexed address inputs permit both a reduction in pins to the standard l6-pin package configuration and an increase in system densities.
