10) May or may not be bank-specific; if multiple banks are to be precharged, each must be in a valid state for precharging.
11) Not bank-specific; BURST TERMINATE affects the most recent READ or WRITE burst, regardless of bank.

1) This table applies when CKEn-1 was HIGH and CKEn is HIGH and after tRC 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 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 orbeen terminated.Write:A WRITE burst has been initiated, with Auto Precharge disabled,
and has not yet terminated or been terminated.Read with AP 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 is in the idle state.Write with AP 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 is in the idle state.
4) AUTO REFRESH, SELF REFRESH and MODE REGISTER SET commands may only be issued when all banks are idle.
5) A BURST TERMINATE command cannot be issued to another bank; it applies to the bank represented by the current state only.
6) All states and sequences not shown are illegal or reserved.
7) READs or WRITEs listed in the Command/Action column include READs or WRITEs with Auto Precharge enabled and READs or WRITEs
with Auto Precharge disabled.
8) Requires appropriate DQM masking.
