Description

This article is about the electronic component M5M44400AJ-7, which belongs to the IC Chip product category. It is a family of dynamic RAMs that are fabricated with high performance CMOS process, specifically designed for large-capacity memory systems that require high speed, low power dissipation, and low cost. This article gives an overview of the features, specifications, application, advantages, and disadvantages of the M5M44400AJ-7.

Specifications and features

The M5M44400AJ-7 features:

• Standard 26 pin SOJ, 26 pin TSOP(II)
• Single 5V±10% supply
• Low stand-by power dissipation
• Low operating power dissipation
• Self refresh capability
• Extended refresh capability
• Hyper-page mode (1024-bit random access), Read-modify-write, RAS-only refresh, CAS before RAS refresh, Hidden refresh
• CBR self refresh(-5S,-6S,-7S) capabilities
• Early-write mode and OE and W to control output buffer impedance
• All inputs, output TTL compatible and low capacitance
• 1024 refresh cycles every 16.4ms (A0~A9)
• 1024refresh cycle every 128ms (A0~A9)
• 4-bit parallel test mode capability

The M5M44400AJ-7 also uses a quadruple-layer polysilicon process combined with silicide technology and a single-transistor dynamic storage stacked capacitor cell to provide high circuit density at reduced costs. Its multiplexed address inputs allow both a reduction in pins and an increase in system densities. Its self or extended refresh current is low enough for battery back-up applications.

Application Scenarios

The M5M44400AJ-7 can be used as the main memory unit for computers, microcomputer memory, refresh memory for CRT, and frame buffer memory for CRT.

Comparison

• High circuit density at reduced costs
• Self or extended refresh current is low enough for battery back-up applications
• Can be used as the main memory unit for computers, microcomputer memory, refresh memory for CRT, and frame buffer memory for CRT
