產品描述

Specifications:
DDR2 667MHz
1)240-pin socket type dual in line memory module (DIMM)
2)Lead-free 1.8V power supply
3)Data rate: 667Mbps
4)1.8V (SSTL-18 compatible) I/O
5)Double-data-rate architecture: two data transfers per clock cycle
6)Bi-directional, differential data strobe (DQS and /DQS) is transmitted/received with data,
to be used in capturing data at the receiver
7)DQS is edge aligned with data for reading: center aligned with data for writing
8)Differential clock inputs (CK and /CK)
9)DLL aligns DQ and DQS transitions with CK transitions
10)Commands entered on each positive CK edge: data and data mask referenced to both edges of DQS
11)Four internal banks for concurrent operation (component)
12)Data mask (DM) for write data
13)Burst lengths: 4, 8
14)CAS latency (CL): 3, 4, 5
15)Auto precharge operation for each burst access
16)Auto refresh and self refresh modes
17)7.8us average periodic refresh interval
18)Posted CAS by programmable additive latency for better command and data bus efficiency
19)Off-chip-driver impedance adjustment and on-die-termination for better signal quality
20)DQS can be disabled for single-ended data strobe operation
