Burst Length
burst oriented, with the burst length being program-
mable, as shown in Figure 5, Mode Register Definition
Diagram. The burst length determines the maximum
number of column locations that can be accessed for a
given READ or WRITE command. Burst lengths of 2, 4,
or 8 locations are available for both the sequential and
the interleaved burst types.
operation or incompatibility with future versions may
result.
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 within the
block if a boundary is reached. The block is uniquely
selected by A1–Ai when the burst length is set to two,
by A2–Ai when the burst length is set to four and by
A3–Ai when the burst length is set to eight (where Ai is
the most significant column address bit for a given
configuration. See Note 5 of Table 6, Burst Definition
Table, on page 10, for Ai values). The remaining (least
significant) address bit(s) is (are) used to select the
starting location within the block. The programmed
burst length applies to both read and write bursts.
Burst Type
to be either sequential or interleaved; this is referred to
as the burst type and is selected via bit M3.
mined by the burst length, the burst type and the start-
ing column address, as shown in Table 6, Burst
Definition Table, on page 10.
Read Latency
between the registration of a READ command and the
availability of the first bit of output data. The latency
can be set to 2, 2.5, or 3 clocks, as shown in Figure 6,
CAS Latency Diagram, on page 10.
and the latency is m clocks, the data will be available
nominally coincident with clock edge n + m. The CAS
Latency Table indicates the operating frequencies at
which each CAS latency setting can be used.
