DO n = Data Out from column n
PRE = PRECHARGE, ACT = ACTIVE, RA = Row Address, BA = Bank Address
Burst Length = 4 in the case shown
3 subsequent elements of Data Out are provided in the programmed order following DO n
DIS AP = Disable Autoprecharge
* = ”Don't Care”, if A10 is HIGH at this point
NOP commands are shown for ease of illustration; other commands may be valid at these times
Note that tRCD > tRCD MIN so that the same timing applies if Autoprecharge is enabled (in which case tRAS
would be limiting)
