DDR SDRAM
Rev. 2.2 Mar. ’03
Double-data-rate architecture; two data transfers per clock cycle
Bidirectional data strobe(DQS)
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
LDM,UDM/DM for write masking only
Auto & Self refresh
7.8us refresh interval(8K/64ms refresh)
Maximum burst refresh cycle : 8
