Precharge
The Precharge command is used to deactivate the open row in a particular bank or the open row in all banks. The
bank(s) is available for a subsequent row access some specified time (t
RP
) after the Precharge command is
issued. Input A10 determines whether one or all banks are to be precharged, and in the case where only one bank
is to be precharged, inputs BA0, BA1 select the bank. When all banks are to be precharged, inputs BA0, BA1 are
treated as “Don’t Care.” Once a bank has been precharged, it is in the idle state and must be activated prior to any
Read or Write commands being issued to that bank.
