Data from any READ burst may be concatenated with data from a subsequent READ command. In either case, a continuous
flow of data can be maintained. A READ command can be initiated on any clock cycle following a previous READ command,
and may be performed to the same or a different (active) bank. The first data element from the new burst follows either the last
element of a completed burst (Figure 15) or the last desired data element of a longer burst which is being truncated
(Figure 16). The new READ command should be issued x cycles after the first READ command, where x equals the number
of desired data elements.
