What is SDRAM?
SDRAM is Synchronous Dynamic RAM.
SDRAM is a variant of DRAM in which the memory speed is synchronized with the clock pulse from the CPU.
This synchronization enables the SDRAM to pipeline read and write requests. Pipelining enables the SDRAM to accept commands at the same time as it is processing other commands.
There are three variants of SDRAM:
- Single Data Rate SDRAM - SDR SDRAM
- Dual Data Rate SDRAM - DDR SDRAM
- Dual Data Rate 2 SDRAM - DDR2 SDRAM
