What is DDRx?

DDRx (Double Data Rate) refers to a family of synchronous dynamic random-access memory (SDRAM) technologies. It's a type of computer memory used in PCs, laptops, and other devices to store data that the CPU is actively using. The 'x' in DDRx indicates the generation of DDR SDRAM, with common versions being DDR, DDR2, DDR3, DDR4, and DDR5. Each generation offers increased speed, bandwidth, and efficiency compared to its predecessor. DDR memory is commonly used for main system memory (RAM) to improve performance by enabling faster data access.
