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
