DESCRIPTION
The W3DG72128V is a 128Mx72 synchronous DRAM module which consists of nine 128Mx8 stacks of 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 64Mx72 SDRAM.
