The D41264C-12 is a DRAM (Dynamic Random-Access Memory) chip manufactured by NEC. Below are the factual specifications, descriptions, and features of this component:

Specifications:

• Manufacturer: NEC
• Part Number: D41264C-12
• Type: DRAM (Dynamic RAM)
• Density: 256Kbit (64K x 4-bit organization)
• Speed: 120ns (12 in the part number indicates 120ns access time)
• Voltage: 5V (standard TTL levels)
• Package: 16-pin DIP (Dual In-line Package)
• Operating Temperature: Commercial (0°C to +70°C) or Industrial (-40°C to +85°C), depending on variant

Descriptions:

• The D41264C-12 is a high-speed, low-power DRAM chip designed for use in computer memory systems.
• It features a 64K x 4-bit organization, meaning it stores 64K addresses, each containing 4 bits of data.
• The chip is commonly used in older computer systems, industrial controllers, and embedded applications requiring moderate memory capacity.

Features:

• Fast access time: 120ns
• Low power consumption (typical for DRAM technology of its era)
• Single 5V power supply
• Standard TTL-compatible inputs and outputs
• Refresh required: Like all DRAMs, it needs periodic refresh cycles to retain data.
• 16-pin DIP package for easy integration into legacy systems.

This chip was widely used in 1980s and early 1990s computing systems, including early PCs, workstations, and industrial control boards.
