NOTE:
1. This table applies when CKE
n-1
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.
