M5M44800CJ,TP-5,-6,-7,-5S,-6S,-7S is a family of 524288-word by 8-bit dynamic RAMs fabricated with the high performance CMOS process, and is ideal for large- capacity memory systems where high speed, low power dissipation, and low costs are essential.
This document describes the M5M44800CJ, TP-5, TP-6, and TP-7 family of 4194304-bit (524288-word by 8-bit) Dynamic RAMs fabricated with high performance CMOS process. These devices are designed for large-capacity memory systems requiring high speed, low power dissipation, and low costs, utilizing a double-layer metalization process and single-transistor dynamic storage stacked capacitor cell.
The datasheet details the electrical characteristics, timing requirements, and absolute maximum ratings for various speed grades (TP-5, TP-6, TP-7). Key features include fast page mode for 1024-column random access, read-modify-write capability, and multiple refresh modes including self-refresh and extended refresh. The device operates from a single 5V supply and is available in 28-pin SOJ and TSOP packages.
