READs
READ bursts are initiated with a READ command, as shown in Figure 10 on page 23.
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
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 CL after the READ command. Each subsequent data-out
element will be valid by the next positive clock edge. Figure 11 on page 24 shows general
timing for each possible CL setting.
Upon completion of a burst, assuming no other commands have been initiated, the DQs
will go High-Z. A full-page burst will continue until terminated. (At the end of the page, it
will wrap to column 0 and continue.)
