Transcend 512MB SDRAM 144Pin SO-DIMM PC133 Unbuffer Non-ECC Memory TS64MSS64V6F User Manual

 

 

 

 

 

Module (S.O.DIMM), mounted 16 pieces of 256-Mbit 

SDRAM sealed in TSOP package and 1 piece of serial 

EEPROM (2-kbit) for Presence Detect (PD). An outline of 

the products is 144-pin Zig Zag Dual tabs socket type 

compact and thin package. Therefore, they make high 

density mounting possible without surface mount 

technology. They provide common data inputs and outputs. 

Decoupling capacitors are mounted beside TSOP on the 

module board. Note: Do not push the cover or drop the 

modules in order to protect from mechanical defects, which 

would be electrical defects.
