DDR2 memory

DDR2 SDRAM - which stands for Double Data Rate Two Synchronous Dynamic Random Access Memory (yes, quite a mouthful) - is the consumer standard memory at the moment. It is SDRAM technology, which itself is part of the DRAM family. DDR2 replaced the original DDR. They are not compatible with each other, since they have different pin counts and module layout. DDR3 is the most recent version of memory and is gradually being introduced as computer processor speeds increase.
