MK4801AN-90 is a 1K x 1-bit dynamic RAM (DRAM) manufactured by MOSTEK.

The MK4801AN-90 is a 1K x 1-bit dynamic RAM (DRAM) manufactured by MOSTEK.

Specifications:

  • Organization: 1K x 1-bit (1024 words x 1-bit)
  • Technology: Dynamic RAM (DRAM)
  • Access Time: 90 ns
  • Operating Voltage: +5V
  • Refresh Requirement: Requires periodic refresh cycles (typically every 2 ms)
  • Package: 16-pin DIP (Dual In-line Package)
  • Operating Temperature Range: Commercial (0°C to +70°C) or Industrial (-40°C to +85°C)

Descriptions:

The MK4801AN-90 is an early-generation DRAM chip designed for low-cost, high-density memory applications. It was commonly used in early microcomputers and embedded systems. Due to its dynamic nature, it requires external refresh circuitry to maintain data integrity.

Features:

  • Low power consumption
  • Single +5V power supply
  • Fully static operation (no clock required)
  • TTL-compatible inputs and outputs
  • Standard 16-pin DIP package for easy integration

This chip was part of MOSTEK's memory lineup during the late 1970s and early 1980s, providing a cost-effective solution for memory expansion in early computing systems.
