SDR DRAM does not have DQS signal, this is called data strobe and data is called DQ. On the other hand, DDR RAMs have DQS signal which makes them somehow achieve higher data rates.
A single DQS may exist for 4, 8, 16 or even 32 DQ signals. Why do we need a DQS? It seems to behave similar to clock. Also, why don't we always have a single DQS for all DQ always, regardless of how many DQ lines exist?
