Data Sheet
1.8 V
1.8 V
DRAM organisations with 4, 8 and 16 data
in/outputs
Double Data Rate architecture: two data transfers
per clock cycle, four internal banks for concurrent
operation
CAS Latency: (2), 3, 4 and 5
Burst Length: 4 and 8
Differential clock inputs (CK and CK)
Bi-directional, differential data strobes (DQS and
DQS) are transmitted / received with data. Edge
aligned with read data and center-aligned with write
data.
DLL aligns DQ and DQS transitions with clock
DQS can be disabled for single-ended data strobe
operation
