READ Command
COMMAND
READ bursts are initiated with a READ command, as shown in Figure 12.
The starting column and bank addresses are provided with the READ command, and
auto precharge is either enabled or disabled for that burst access. If auto precharge is
enabled, the row being accessed is precharged at the completion of the burst. For the
READ commands used in the following illustrations, auto precharge is disabled.
During READ bursts, the valid data-out element from the starting column address will
be available following CL after the READ command. Each subsequent data-out element
will be valid by the next positive clock edge. Figure 13 on page 28 shows general timing
for each possible CL setting.
