NOTE:
1. This table applies when CKEn-1 was HIGH and CKEn is HIGH (see Table 7 on page 41) and after
tXSNR has been met (if the
previous state was self refresh).
2. This table is bank-specific, except where noted (i.e., the current state is for a specific bank and the commands shown are
those allowed to be issued to that bank when in that state). Exceptions are covered in the notes below.
3. Current state definitions:
Idle:
The bank has been precharged, and tRP has been met.
Row Active:
A row in the bank has been activated, and tRCD 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.
4. The following states must not be interrupted by a command issued to the same bank. COMMAND INHIBIT or NOP com-
mands, or allowable commands to the other bank should be issued on any clock edge occurring during these states.
Allowable commands to the other bank are determined by its current state and Table 8, Truth Table – Current State
Precharging:
Starts with registration of a PRECHARGE command and ends when tRP is met. Once
tRP is met, the bank will be in the idle state.
Row Activating:
Starts with registration of an ACTIVE command and ends when tRCD is met. Once
tRCD is met, the bank will be in the “row active” state.
Read w/Auto-Precharge
Enabled:
Starts with registration of a READ command with auto precharge enabled and
ends when tRP has been met. Once tRP 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 tRP has been met. Once tRP is met, the bank will be in the idle state.
