Burst Write with Auto-Precharge
If A10 is high when a Write Command is issued, the Write with Auto-Precharge function is engaged. The DDR2 SDRAM
automatically begins precharge operation after the completion of the write burst
plus the
write recovery time delay (WR),
programmed
in the MRS register, as long as tRAS is satisfied. The bank undergoing Auto-Precharge from the completion of
the write burst may be reactivated if the following two conditions are satisfied.
(1) The last data-in to bank activate delay time (tDAL = WR + tRP) has been satisfied.
(2) The RAS cycle time (tRC) from the previous bank activation has been satisfied.
Examples:
Burst Write with Auto-Precharge (tRC Limit): WL = 2, tDAL = 6 (WR = 3, tRP = 3), BL = 4
