The PRECHARGE command 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 subsequent row access a
specified time (
whether one or all banks are to be precharged, and in the case where only one bank is
precharged, inputs BA0 and BA1 select the bank. Otherwise BA0 and BA1 are treated as
“Don’t Care.” After a bank has been precharged, it is in the idle state and must be activa-
ted prior to any READ or WRITE commands are issued to that bank.
BA0, BA1
The BURST TERMINATE command is used to truncate either fixed-length or continu-
ous page bursts. The most recently registered READ or WRITE command prior to the
BURST TERMINATE command is truncated.
AUTO REFRESH is used during normal operation and is analogous to CAS#-BEFORE-
RAS# (CBR) REFRESH in FPM/EDO DRAM. Addressing is generated by the internal
refresh controller. This makes the address bits “Don’t Care” during an AUTO REFRESH
command.
