HYB25D128400/800/160AT(L)
128-Mbit Double Data Rate SDRAM
Write to Precharge: Minimum DQSS, Odd Number of Data (1 bit Write), Interrupting
(Burst Length = 4 or 8)
DI a-b = data in for bank a, column b.
An interrupted burst is shown, 1 data element is written.
t
W
R
is referenced from the first positive CK edge after the last desired data in pair.
The Precharge command masks the last 2 data elements in the burst.
A10 is Low with the
W
rite command (Auto Precharge is disabled).
1 = Can be don
'
t care for programmed burst length of 4.
2 = For programmed burst length of 4, DQS becomes don
'
t care at this point.
3 = This bit is correctly written into the memory array if DM is low.
4 = These bits are incorrectly written into the memory array if DM is low.
