The D4164D-2 is a 64Kbit Dynamic RAM (DRAM) manufactured by NEC. This memory chip is designed for use as main memory in various computer systems and electronic devices. DRAM offers high density and relatively low cost, making it a popular choice for applications requiring large amounts of volatile memory. The device requires periodic refreshing to maintain data integrity.

Applications:

• Computer Main Memory
• Video RAM
• Buffer Memory
• Graphics Cards
• Data Storage for Electronic Devices

Features:

• 64 Kbit (65,536 x 1) memory organization
• Fast Access Time (-2 indicates faster access time than other variants)
• Single 5V Power Supply
• TTL Compatible Inputs/Outputs
• Multiplexed Address Inputs
• Requires periodic refresh

Benefits:

• Provides high-density memory storage for computer systems and electronic devices.
• Enables fast data access with its quick access time, improving system performance.
• Simplifies system design with single 5V power supply requirement.
• Offers compatibility with standard TTL logic circuits.
• Reduces pin count with multiplexed address inputs, saving board space.
• Cost-effective solution for large memory requirements.

Additional Details:

The D4164D-2 operates from a single 5V power supply and features TTL-compatible inputs and outputs, making it easy to interface with a wide range of microprocessors and microcontrollers. The memory array is organized as 65,536 locations of 1 bit each. The access time of the D4164D-2 is relatively fast compared to other versions of this chip, which is indicated by the '-2' suffix. The device uses multiplexed address inputs to reduce the number of pins required. Because it is a DRAM, the contents must be refreshed periodically to prevent data loss. The D4164D-2 is packaged in a standard DIP (Dual In-Line Package). It provides a reliable and cost-effective solution for volatile memory requirements in a variety of applications.
