128MB- 16M x 64 SDRAM UNBUFFERED
FEATURES
DESCRIPTION
n Burst Mode Operation
The WED3DG6418V is a 16Mx64 synchronous DRAM module
which consists of eight 16Mx8 SDRAM components in TSOP- 11
package and one 2K EEPROM in an 8- pin TSSOP package for
Serial Presence Detect which are mounted on a 168 Pin DIMM
multilayer FR4 Substrate.
n Auto and Self Refresh capability
n LVTTL compatible inputs and outputs
n Serial Presence Detect with EEPROM
n Fully synchronous: All signals are registered on the positive
edge of the system clock
n Programmable Burst Lengths: 1, 2, 4, 8 or Full Page
n 3.3 volt 6 0.3v Power Supply
n 168- Pin DIMM JEDEC
