Once the burst of write data is concluded and given that no subsequent burst write operations are initiated,

the data strobe signal (DQS) transitions from a logic low level back to Hi-Z. This is referred to as the data

strobe “write postamble”. This transition happens nominally one-half clock period after the last data of the

burst cycle is latched into the device.
