DESCRIPTION
The WED3DG72128V is a 128Mx72 synchronous DRAM
module which consists of eighteen 128Mx4 stack SDRAM
components in TSOP II package, two 18 bit Drive ICs for
input control signal and one 2Kb EEPROM in an 8 pin
TSSOP package for Serial Presence Detect which are
mounted on a 168 pin DIMM multilayer FR4 Substrate.
