DDR Insights | Sumble

What is DDR?

DDR (Double Data Rate) SDRAM is a type of synchronous dynamic random-access memory (SDRAM) with double the bandwidth of single data rate (SDR) SDRAM. It achieves this by transferring data on both the rising and falling edges of the clock signal. DDR memory is commonly used in computers, graphics cards, and other devices where high bandwidth memory access is required for performance.
