DESCRIPTION

The W3DG648V is a 2x4Mx64 synchronous DRAM module which consists of eight 4Mx16 SDRAM components in TSOP II package, and one 2Kb EEPROM in an 8 pin TSSOP package for Serial Presence Detect which are mounted on a 144 pin SO-DIMM multilayer FR4 Substrate.

This module is structured as 2 ranks of 8Mx64 SDRAM.
