In a DDR memory, during a read, output data from the DDR is aligned on the strobe. There is one strobe per 8-bit:
- UDQS/LDQS for a 16-bit-wide DDR
- DQS[0-3] for a 32-bit-wide DDR
Is there any significant delta between the strobes of the same DDR chip? 'Significant' means: can I use one strobe for all the bit? I have a custom-made DDR controller in a FPGA and I would like to use one strobe for the entire data set.
