Subject: [SI-LIST] : DDR SDRAM DQS vs DQ
Can anyone tell me why JEDEC specifies in DDR SDRAM spec that DQS is
edge-aligned
with data when reading from SDRAM, while center-aligned with data when
writing to SDRAM?
I don't see any reason why SDRAM cannot send out data with center-aligned
strobe.
Regards,
Ken
