Additional preview pages of the WED3EG7218S-JD3 datasheet.

The WED3EG7218S is a 16Mx72 Double Data Rate SDRAM memory module based on 128Mb DDR SDRAM component.

The module consists of nine 16Mx8 DDR SDRAMs in 66 pin TSOP packages mounted on a 184 pin FR4 substrate.

Synchronous design allows precise cycle control with the use of system clock.

Double-data-rate architecture DDR200, DDR266, DDR333 and DDR400.
JEDEC design speciﬁed BI-directional data strobes (DQS) Differential clock inputs (CK & CK#) Programmable Read Latency 2,2.5 (clock) Programmable Burst Length (2,4,8) Programmable Burst type (sequential & interleave) Edge aligned data output, center aligned data input. Auto and self refresh Serial presence detect Power supply:.
VCC = VCCQ = 2.5V±0.2V (100, 133 and 166MHz).
VCC = VCCQ = 2.6V±0.1V (200MHz).
