Specifications / Features
|
- Density : 1GB / 2GB
- Package: 240-pin dual in line memory module (U-DIMM)
- Power supply: VDD = 1.8V ~ 2.2V
- Frequency: 800 / 1066 / 1150 / 1200Mhz
- Interface: SSTL_18

- /CAS Latency (CL): 3, 4, 5, 6
- Precharge: auto precharge option for each burst access
- Refresh: auto-refresh, self-refresh
- Refresh cycles: 8192 cycles/64ms
-Average refresh period
7.8 µs at 0'C <= TC <= +85'C
3.9 µs at +85'C < TC <= +95'C
- Double-data-rate architecture; two data transfers per clock cycle
- The high-speed data transfer is realized by the 4 bits prefetch pipelined architecture
- Bi-directional differential data strobe (DQS and /DQS) is transmitted/received with data for 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
- Data mask (DM) for write data
- 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
- Serial presence detect with EEPROM
- All of Lead-free products are compliant for RoHS
