in a given time
RDRAM (Rambus Dynamic Random Access Memory) – It is desined to transfer
data at faster rate. It is the faster computer memory.
DDR-1 – It is also known as the Dual Data Rate SDRAM.Its spacification
are:
Pin- 168, Cut – 2, FSB- 100-133mz, operating voltage – 3.3v, Storage
capacity128mb-1gb.
DDR-2 – It was launched in 2007. Its spacification are:
Pin - 184, Cut-1, FSB-
153mz-400mz, operating voltage 2.5,Storage Capacity 128mb- 2gb
DDR-3 – DDR-3 RAM is similar toDDR-2 RAM but uses 30% less power and can
transfer data twice as fast.
