W971GG8JB-25 General Description
SDRAM - DDR2 Memory IC 1Gbit Parallel 200 MHz 57.5 ns 60-WBGA (8x12.5)
Features
Power Supply: VDD, VDDQ = 1.8 V0.1 V
Double Data Rate architecture: two data transfers per clock cycle
CAS Latency: 3, 4, 5, 6 and 7
Burst Length: 4 and 8
Bi-directional, differential data strobes (DQS and DQS ) are transmitted / received with data
Edge-aligned with Read data and center-aligned with Write data
DLL aligns DQ and DQS transitions with clock
Differential clock inputs (CLK and CLK )
Data masks (DM) for write data.
Commands entered on each positive CLK edge, data and data mask are referenced to both edges of DQS
Posted CAS programmable additive latency supported to make command and data bus efficiency
Read Latency = Additive Latency plus CAS Latency (RL = AL + CL)
Off-Chip-Driver impedance adjustment (OCD) and On-Die-Termination (ODT) for better signal quality
Auto-precharge operation for read and write bursts
Auto Refresh and Self Refresh modes
Precharged Power Down and Active Power Down
Write Data Mask
Write Latency = Read Latency - 1 (WL = RL - 1)
Interface: SSTL_18
Packaged in WBGA 60 Ball (8x12.5 mm2), using Lead free materials with RoHS compliant
