tions that can be accessed for a given READ or WRITE command. Burst lengths of 2, 4,
8, or 16 locations are available for both sequential and interleaved burst types.
When a READ or WRITE command is issued, a block of columns equal to the burst
length is effectively selected. All accesses for that burst take place within this block,
meaning that the burst will wrap when a boundary is reached. The block is uniquely
selected by A[i:1] when BL = 2, by A[i:2] when BL = 4, by A[i:3] when BL = 8, and by A[i:4]
when BL = 16, where Ai is the most significant column address bit for a given configura-
tion. The remaining (least significant) address bits are used to specify the starting
location within the block. The programmed burst length applies to both READ and
WRITE bursts.
Accesses within a given burst can be programmed to be either sequential or interleaved
via the standard mode register.
The ordering of accesses within a burst is determined by the burst length, the burst
type, and the starting column address.
