Burst Mode Operation
The WED3DG7268V is a 64Mx72 synchronous
DRAM module which consists of nine 64Mx8 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.
Auto and Self Refresh capability
LVTTL compatible inputs and outputs
Serial Presence Detect with EEPROM
Fully synchronous: All signals are registered on the positive
edge of the system clock
