Precharge Termination in WRITE Cycle
During 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 t
RP
from the precharge command. The DQM must be high to mask
invalid data in.
During WRITE cycle, the write data written prior to the precharge command will be correctly stored. However, invalid
data may be written at the same clock as the precharge command. To prevent this from happening, DQM must be high
at the same clock as the precharge command. This will mask the invalid data.
