Write Operation
The burst length (BL) and the burst type (BT) of the mode register are referred when a write command is issued.
The burst length (BL) determines the length of a sequential data input by the write command that can be set to 2, 4
or 8. The latency from write command to data input is fixed to 1. The starting address of the burst write is defined
by the column address, the bank select address (See “Pin Function”) in the cycle when the write command is issued.
DQS should be input as the strobe for the input-data and DM as well during burst operation. tWPRE prior to the first
rising edge of DQS, DQS must be set to low. tWPST after the last falling edge of DQS, the DQS pins can be
changed to high-Z. The leading low period of DQS is referred as write preamble. The last low period of DQS is
referred as write postamble.
