2. Double data rate

Technology & Computing · Computer Hardware Abbreviations

Type of SDRAM that transfers data on both the rising and falling edges of the clock signal, doubling bandwidth without raising the clock frequency. Generations from DDR to DDR5 have been the main memory of PCs since about 2000.

Example: Check whether the motherboard takes DDR4 or DDR5 before buying RAM.

JEDEC, the semiconductor standards body, defines each generation: DDR (2000), DDR2 (2003), DDR3 (2007), DDR4 (2014) and DDR5 (2020). Modules of different generations have the key notch in different places, so they cannot be installed in the wrong slot. Speeds are quoted in megatransfers per second (MT/s), often loosely written as MHz.
