DDR SDRAM 256Mb E-die (x4, x8) Pb-Free
Rev. 1.1 October, 2004
Double-data-rate architecture; two data transfers per clock cycle
Bidirectional data strobe
[DQ] (x4,x8)
Four banks operation
Differential clock inputs(CK and CK)
DLL aligns DQ and DQS transition with CK transition
MRS cycle with address key programs
-. Read latency 2, 2.5 (clock)
-. Burst length (2, 4, 8)
-. Burst type (sequential & interleave)
All inputs except data & DM are sampled at the positive going edge of the system clock(CK)
Data I/O transactions on both edges of data strobe
Edge aligned data output, center aligned data input
DM for write masking only (x4, x8)
Auto & Self refresh
7.8us refresh interval(8K/64ms refresh)
Maximum burst refresh cycle : 8
