During the 1990s synchronous dynamic RAM (SDRAM) became standard because it synchronized with the computer’s system clock. It was later replaced by DDR-SDRAM, or double data rate synchronous dynamic RAM, which transferred data twice per clock cycle for greater efficiency. Later generations—DDR2, DDR3, DDR4, and DDR5—offered faster speeds, higher capacities, greater bandwidth, and lower power consumption. DDR4 became common in the 2010s, and DDR5 improved performance for artificial intelligence, gaming, and high-performance computing applications.
