- 240-pin socket type dual in line memory module (DIMM)
- Lead-free
- 1.8V power supply
- Data rate: 800Mbps
- 1.8V (SSTL_18 compatible) I/O
- Double-data-rate architecture: two data transfers perclock 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: centeraligned 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 (Component)
- 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
- 7.8us average periodic refresh interval
- 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
