The W9812G6KH-75 is a 128M x 8 bits Double Data Rate (DDR) Synchronous DRAM (SDRAM) manufactured by Winbond Electronics. DDR SDRAM is a type of dynamic random-access memory that transfers data on both the rising and falling edges of the clock signal, effectively doubling the data transfer rate compared to single data rate SDRAM.
Applications:
- Computer Memory: Used as main system memory in desktop and laptop computers.
- Graphics Cards: Found in graphics cards to store textures, frame buffers, and other graphics-related data.
- Embedded Systems: Used in embedded systems such as networking equipment, industrial controllers, and consumer electronics.
- Gaming Consoles: Used as system memory in gaming consoles.
- Telecommunications Equipment: Found in routers, switches, and other telecommunications equipment.
Features:
- 1 Gigabit Capacity: Offers a storage capacity of 1,073,741,824 bits (128 Megabytes).
- DDR SDRAM: Utilizes Double Data Rate (DDR) technology for high-speed data transfer.
- Synchronous Operation: Operates synchronously with a clock signal.
- Data Masking: Supports data masking for selective data writes.
- Auto Refresh: Includes auto refresh functionality to maintain data integrity.
- Single 2.5V Power Supply: Operates on a single 2.5-volt power supply.
- -75 Speed Grade: The "-75" suffix indicates a speed grade of 133 MHz (7.5ns cycle time).
Benefits:
- High-Speed Data Transfer: Provides high-speed data transfer for improved system performance.
- Large Storage Capacity: Offers a large storage capacity for demanding applications.
- Low Power Consumption: Consumes minimal power, making it suitable for power-sensitive devices.
