SD_CLK is one SDRAM clock in (ns).
Pulse width high plus pulse width low cannot exceed min and max clock period.
Command output valid should be 1/2 the memory bus clock (SD_CLK) plus some minor adjustments for process, temperature,
and voltage variations.
This specification relates to the required input setup time of today’s DDR memories. The processor’s output setup should be
larger than the input setup of the DDR memories. If it is not larger, the input setup on the memory is in violation.
MEM_DATA[31:24] is relative to MEM_DQS[3], MEM_DATA[23:16] is relative to MEM_DQS[2], MEM_DATA[15:8] is relative to
MEM_DQS[1], and MEM_[7:0] is relative MEM_DQS[0].
The first data beat is valid before the first rising edge of DQS and after the DQS write preamble. The remaining data beats are
valid for each subsequent DQS edge.
This specification relates to the required hold time of today’s DDR memories. MEM_DATA[31:24] is relative to MEM_DQS[3],
MEM_DATA[23:16] is relative to MEM_DQS[2], MEM_DATA[15:8] is relative to MEM_DQS[1], and MEM_[7:0] is relative
MEM_DQS[0].
Data input skew is derived from each DQS clock edge. It begins with a DQS transition and ends when the last data line
becomes valid. This input skew must include DDR memory output skew and system level board skew (due to routing or other
factors).
Data input hold is derived from each DQS clock edge. It begins with a DQS transition and ends when the first data line
becomes invalid.
