DON'T CARE
* = "Don't Care", if A10 is HIGH at this point; A10 must be HIGH if more than one bank is active (i.e. must precharge all active banks)
PRE = PRECHARGE, ACT = ACTIVE, RA = Row Address, BA = Bank Address, AR = AUTOREFRESH
NOP commands are shown for ease of illustration; other valid commands may be possible at these times
DM, DQ and DQS signals are all "Don't Care"/High-Z for operations shown
