The listing, 2 ASint DDR2 2GB RAM Sticks. (4GB total). SLZ2128M8-JGE2C. has ended.

240-pin socket type dual in line memory module (DIMM)
-PCB height: 30.0mm
-Lead pitch: 1.0mm
-Lead-free
Power supply: VDD, VDDQ = 1.8V ± 0.1V
Data rate: 667Mbps/800Mbps (max.)
SSTL_18 compatible I/O
Double-data-rate architecture: two data transfers per clock cycle
Bi-directional, differential data strobe (DQS and /DQS) is transmitted/received with data, to be used in capturing data at the receiver
DQS is edge aligned with data for READs: center-aligned with data for WRITEs
Differential clock inputs (CK and /CK)
DLL aligns DQ and DQS transitions with CK transitions
Commands entered on each positive CK edge: data and data mask referenced to both edges of DQS
Four internal banks for concurrent operation (components)
Data mask (DM) for write data
Burst lengths: 4, 8
/CAS Latency (CL): 3, 4, 5
Auto precharge operation for each burst access
Auto refresh and self refresh modes
Average refresh period
-7.8μs at 0°C ? TC ? +85°C
-3.9μs at +85°C＜TC ? +95°C
Operating case temperature range
-TC = 0°C to +95°C
Posted CAS by programmable additive latency for better command and data bus efficiency
Off-Chip-Driver Impedance Adjustment and On-Die-Termination for better signal quality
/DQS can be disabled for single-ended Data Strobe operation
