DDR, or Double Data Rate, is a type of computer memory technology that allows data to be transferred on both the rising and falling edges of the clock signal. This effectively doubles the data transfer rate compared to earlier memory types, such as SDR (Single Data Rate). DDR is commonly used in RAM (Random Access Memory) for computers and other devices, enhancing performance and speed. There are several generations of DDR, including DDR2, DDR3, DDR4, and the latest, DDR5. Each generation offers improvements in speed, efficiency, and power consumption. DDR memory is essential for modern computing, enabling faster processing and better multitasking capabilities.
