Precharge Termination in WRITE Cycle
During a write cycle, the burst write operation is terminated by a precharge command. When the precharge
command is issued, the burst write operation is terminated and precharge starts. The same bank can be activated
again after tRP from the precharge command. To issue a precharge command, tRAS must be satisfied.
The write data written up to two clocks prior to the precharge command will be correctly stored. However, invalid
data may be written at the same clock as the precharge command and one clock before the precharge command.
To prevent this from happening, DQM must be high and mask the invalid data.
