Applications:

• Personal Computers: Used in older PCs as main system memory (RAM).
• Graphics Cards: Employed as video RAM (VRAM) in graphics adapters.
• Printers: Utilized in printer memory for image processing and data storage.
• Industrial Control Systems: Integrated into embedded systems for storing and processing data.
• Video Game Consoles: Can be found in the memory systems of older video game consoles.

Features:

• Capacity: 262,144 bits (256Kbit).
• Organization: Typically arranged as 64K x 4 bits.
• Access Time: Features an access time of 120 ns.
• Refresh: Requires periodic refresh cycles to maintain data integrity.
• Power Consumption: Operates with a standard 5V power supply.
• Package: Available in package types like DIP (Dual In-line Package) and SOJ (Small Outline J-lead).

Benefits:

• Cost-Effective: Offers a reasonably priced memory option where high density isn't critical.
• Moderate Speed: Provides relatively quick data storage and retrieval.
• Standard Interface: Compatible with standard DRAM controllers.
• Widely Used: A common component in many electronic devices of its era.

Additional Details:

The UPD41464C-12 needs periodic refresh cycles to retain stored data, which is a fundamental characteristic of DRAM. Operating temperature generally ranges from 0°C to 70°C. Careful handling is necessary to avoid electrostatic discharge (ESD) damage. Refer to the manufacturer's datasheet for detailed electrical specifications and application guidelines. Address multiplexing is used to reduce the number of address pins required.
