COMMAND
1.
2.
READ bursts are initiated with a READ command, as shown in Figure 8 on page 21.
The starting column and bank addresses are provided with the READ command, and
auto precharge either is 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
generic 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 the CAS latency after the READ command. Each subsequent data-
out element will be valid by the next positive clock edge. Figure 9 on page 22 shows
general timing for each possible CAS latency setting.
