HY53C464LS-80** is a high-speed CMOS dynamic random-access memory (DRAM) chip manufactured by Hyundai Electronics (now SK Hynix).

The HY53C464LS-80 is a high-speed CMOS dynamic random-access memory (DRAM) chip manufactured by Hyundai Electronics (now SK Hynix). Below are its key specifications, descriptions, and features:

Specifications:

  • Type: 4M x 16-bit (64Mb) DRAM
  • Organization: 4,194,304 words × 16 bits
  • Access Time: 80ns
  • Operating Voltage: 5V ±10%
  • Package: 42-pin SOJ (Small Outline J-Lead)
  • Refresh Cycles: 4,096 cycles every 64ms
  • Operating Temperature Range: 0°C to 70°C (Commercial)
  • Interface: TTL-compatible

Descriptions:

  • Designed for high-performance computing and embedded applications.
  • Uses a multiplexed address bus (row and column addresses share the same pins).
  • Requires periodic refresh cycles to maintain data integrity.

Features:

  • Fast Page Mode (FPM) operation for improved sequential access speed.
  • CAS-before-RAS (CBR) refresh support.
  • Low power consumption in standby mode.
  • Single 5V power supply operation.
  • TTL-compatible inputs and outputs for easy interfacing.

This DRAM chip is commonly used in older computer systems, workstations, and industrial applications requiring moderate-speed memory.
