Burst Interruption
Interruption of a read or write burst is prohibited for burst length of 4 and only allowed for burst length of 8
under the following conditions:
1. A Read Burst of 8 can only be interrupted by another Read command. Read burst interruption by a Write or Precharge
Command is prohibited.
2. A Write Burst of 8 can only be interrupted by another Write command. Write burst interruption by a Read or Precharge
Command is prohibited.
3. Read burst interrupt must occur exactly two clocks after the previous Read command. Any other Read burst interrupt
timings are prohibited.
4. Write burst interrupt must occur exactly two clocks after the previous Write command. Any other Read burst interrupt
timings are prohibited.
5. Read or Write burst interruption is allowed to any bank inside the DDR2 SDRAM.
6. Read or Write burst with Auto-Precharge enabled is not allowed to be interrupted.
7. Read burst interruption is allowed by a Read with Auto-Precharge command.
8. Write burst interruption is allowed by a Write with Auto-Precharge command.
9. All command timings are referenced to burst length set in the mode register. They are not referenced to the actual
burst. For example, Minimum Read to Precharge timing is AL + BL/2 where BL is the burst length set in the mode reg-
ister and not the actual burst (which is shorter because of interrupt). Minimum Write to Precharge timing is WL + BL/ 2
+ tWR, where tWR starts with the rising clock after the un-interrupted burst end and not form the end of the actual burst
end.
