The W972GG6KB is a 2G bits DDR2 SDRAM, and speed involving -18, -25/25I, and -3/-3I.

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
