NOTE:
1. This table applies when CKE
was HIGH and CKE
n
is HIGH (see Truth Table 2) and after
t
XSR has been met (if the
previous state was self refresh).
2. This table describes alternate bank operation, except where noted; i.e., the current state is for bank
n
and the
commands shown are those allowed to be issued to bank
m
(assuming that bank
m
is in such a state that the given
command is allowable). Exceptions are covered in the notes below.
3. Current state definitions:
Idle: The bank has been precharged, and
t
RP has been met.
Row Active: A row in the bank has been activated, and
t
RCD has been met. No data bursts/accesses and no
register accesses are in progress.
Read: A READ burst has been initiated, with auto precharge disabled, and has not yet terminated or
been terminated.
Write: A WRITE burst has been initiated, with auto precharge disabled, and has not yet terminated
or been terminated.
Read w/Auto
Precharge Enabled: Starts with registration of a READ command with auto precharge enabled, and ends when
t
RP
has been met. Once
t
RP is met, the bank will be in the idle state.
Write w/Auto
Precharge Enabled: Starts with registration of a WRITE command with auto precharge enabled, and ends when
t
RP
has been met. Once
t
RP is met, the bank will be in the idle state.
