com 1GB Unbuffered DDR2 SDRAM DIMM EBE11ED8AGWA (128M words × 72 bits, 2 Ranks) Specifications • Density: 1GB • Organization  128M words × 72 bits, 2 ranks • Mounting 18 pieces of 512M bits DDR2 SDRAM sealed in FBGA • Package: 240-pin socket type dual in line memory module (DIMM)  PCB height: 30.
0mm  Lead pitch: 1.
0mm  Lead-free (RoHS compliant) • Power supply: VDD = 1.
8V ± 0.
1V • Data rate: 667Mbps/533Mbps (max.
) • Four internal banks for concurrent operation (components) • Interface: SSTL_18 • Burst lengths (BL): 4, 8 • /CAS Latency (CL): 3, 4, 5 • Precharge: auto precharge option for each burst access • Refresh: auto-refresh, self-refresh • Refresh cycles: 8192 cycles/64ms  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 Features • 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-DieTermination for better signal quality • /DQS can be disabled for single-ended Data Strobe operation Document No.
