128MB- 16Mx64 SDRAM UNBUFFERED
FEATURES
DESCRIPTION
The W3DG6416V is a 16Mx64 synchronous DRAM
module which consists of eight 8Mx16 SDRAM
components in TSOP II 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.

Note:
Permanent device damage may occur if "ABSOLUTE MAXIMUM RATINGS" are exceeded.
Functional operation should be restricted to recommended operating condition.
Exposure to higher than recommended voltage for extended periods of time could affect
device reliability.
