PRECHARGE Command
Notes:
The PRECHARGE command (Figure 28) is used to deactivate the open row in a partic-
ular bank or the open row in all banks. The bank(s) will be available for a subsequent row
access some specified time (
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.
1. BA = Bank Address.
A0-A9, A11
All = All banks to be Precharged, BA1, BA0 are “Don't Care.”
Single = Only bank selected by BA1 and BA0 will be precharged.
