Product Summary
Inexpensive and large-capacity SDRAM (Synchronous Dynamic Random Access Memory) is currently used as the main memory of computers.This SDRAM consists of memory cells composed of MOSFETs (Metal-Oxide-Semiconductor Field Effect Transistors) and capacitors, and has a clock-synchronous memory interface.
What is SDRAM?
SDRAM has a memory interface that is controlled by an external clock signal, optimizing data processing capabilities and greatly improving performance.
Structure of SDRAM
The SDRAM routes clock signals through an integrated state machine so that incoming commands can be pipelined.SDRAM allows new instructions to be received while an instruction in progress is being processed. SDRAM is divided equally into small sections of memory cells called banks.
This configuration allows memory interleaving where all banks can be read simultaneously. This unique arrangement results in faster data transfers and higher performance than asynchronous DRAM.
Suitable applications for SDRAM
SDRAM can be used to optimize computing in a huge number of digital electronic devices such as computers, video games and other portable devices.SDRAM is customized for battery-powered technologies and can operate at low power. Such power savings are achieved through operating temperature-dependent refresh or circuit-controlled power-down modes.
Advantages of using SDRAM in electronic equipment
SDRAM is designed to process data at the same clock speed as the CPU, and is positioned as a core component for high-speed processing of large amounts of data. Today, it is widely used in various consumer electronics such as automotive, industrial, network, DTV, DSC, and STB. Winbond offers SDRAM of the highest standard. Winbond offers high quality SDRAM used in commercial and industrial electronic systems. the Company specialty DRAMs are designed to meet high performance standards while maintaining low power consumption.
