the WRITE diagrams show the nominal case, and where the two extreme cases (

(page 108) shows the nominal case and the extremes of
pletion of a burst, assuming no other commands have been initiated, the DQ will re-
main High-Z and any additional input data will be ignored.
Data for any WRITE burst may be concatenated with a subsequent WRITE command to
provide continuous flow of input data. The first data element from the new burst is ap-
plied after the last element of a completed burst. The new WRITE command should be
issued x cycles after the first WRITE command, where x equals BL/2.
Figure 58 (page 109) shows concatenated bursts of BL = 4 and how full-speed random
write accesses within a page or pages can be performed. An example of nonconsecutive
WRITEs is shown in Figure 59 (page 109). DDR2 SDRAM supports concurrent auto pre-
charge options, as shown in Table 43.
DDR2 SDRAM does not allow interrupting or truncating any WRITE burst using BL = 4
operation. Once the BL = 4 WRITE command is registered, it must be allowed to com-
plete the entire WRITE burst cycle. However, a WRITE BL = 8 operation (with auto pre-
charge disabled) might be interrupted and truncated only by another WRITE burst as
long as the interruption occurs on a 4-bit boundary due to the 4n-prefetch architecture
of DDR2 SDRAM. WRITE burst BL = 8 operations may not be interrupted or truncated
with any command except another WRITE command, as shown in Figure 60
(page 110).
Data for any WRITE burst may be followed by a subsequent READ command. To follow
