Description:

The D41264V-12 is a 256Kb (32K x 8) DRAM chip designed for use in early computer systems and embedded applications. It operates at a standard 5V power supply and features a 120ns access time, making it suitable for systems requiring moderate-speed memory.

Features:

• 256Kbit Organization: 32,768 words × 8 bits
• Low Power Consumption: Designed for energy-efficient operation
• Single 5V Supply: Simplifies system power requirements
• 16-pin DIP Package: Industry-standard through-hole mounting
• Multiplexed Addressing: Reduces pin count by sharing row and column addresses
• CAS (Column Address Strobe) Before RAS (Row Address Strobe) Refresh: Supports standard refresh methods

This DRAM chip was commonly used in early PCs, industrial control systems, and other electronics requiring volatile memory storage.
