Read command to Precharge command interval (same bank):
When the precharge command is executed for the same bank as the read command that preceded it, the
minimum interval between the two commands is one clock. However, since the output buffer then becomes
High-Z after the clocks defined by l
HZP
, there is a case of interruption to burst read data output will be
interrupted, if the precharge command is input during burst read. To read all data by burst read, the clocks
defined by l
EP
must be assured as an interval from the final data output to precharge command execution.
