Precharge (PRE/PREALL)

Precharge Command
The Precharge command is used to deactivate the
open row in a particular bank (PRE) or the open rows in
all banks (PREALL). The bank(s) will enter the idle
state and be available again for a new row access after
the time t
RP
. A8/AP sampled with the PRE command
determines whether one or all banks are to be
precharged. For PRE commands BA0 and BA1 select
the bank. For PREALL inputs BA0 and BA1 are “Don’t
Care”. The PRE/PREALL command may not be given
unless the
t
RAS
requirement is met for the selected bank
(PRE), or for all banks (PREALL).
