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 lHZP, 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 lEP must be assured as
an interval from the final data output to precharge command execution.
