Writes 
Write bursts are initiated with a Write command, as shown in timing figure Write Command on 
following: The starting column and bank addresses are provided with the Write command, and Auto 
Precharge is either enabled or disabled for that access. If Auto Precharge is enabled, the row being 
accessed is precharged at the completion of the burst. For the generic Write commands used in the 
following illustrations, Auto Precharge is disabled. 
 
During Write bursts, the first valid data-in element is registered on the first rising edge of DQS 
following the write command, and subsequent data elements are registered on successive edges of 
DQS. The Low state on DQS between the Write command and the first rising edge is known as the 
write preamble; the Low state on DQS following the last data-in element is known as the write 
postamble.
