Burst Write Operation (WRITE)
The Burst Write is initiated by issuing a WRITE command at the rising edge of the clock. The address inputs (A9, A7.. A0) determine
starting column address. Data for the first burst write cycle must be applied on the DQ pins on the first rising edge of DQSx following the
WRITE command. The time between the WRITE command and the first corresponding edge of the data strobe is tDQSS. The remaining
data inputs must be supplied on each subsequent rising and falling edge of the data strobe until the burst length is completed. When the
burst has been finished, any additional data supplied to the DQ pins will be ignored.
