PRECHARGE Command
Note:
COMMAND
The PRECHARGE command shown in Figure 24 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 subse-
quent row access some specified time (
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.” After 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.
