The PRECHARGE command is used to deactivate the open row in a particular bank or
the open row in all banks. The bank(s) will be available for a subsequent row access a
specified time (
whether one or all banks will be precharged, and in the case where only one bank is
precharged, inputs BA0 and BA1 select the bank. Otherwise, BA0 and BA1 are treated as
“Don’t Care.” After a bank has been precharged, it is in the idle state and must be activa-
ted prior to any READ or WRITE commands being issued to that bank.
