Precharge
The precharge command sets the bank selected by pin A11
to the precharged state. This command can be executed at
a time t
RAS
following the execution of an active command to
the same bank. The selected bank goes to the idle state at
a time t
RP
following the execution of the precharge command,
and an active command can be executed again for that
bank.
If pin A10 is low when this command is executed, the bank
selected by pin A11 will be precharged, and if pin A10 is
HIGH, both banks will be precharged at the same time. This
input to pin A11 is ignored in the latter case.
Read Cycle Interruption
Using the Precharge Command
A read cycle can be interrupted by the execution of the
precharge command before that cycle completes. The
delay time (t
RQL
) from the execution of the precharge
command to the completion of the burst output is the
clock cycle of
CAS
latency.
