These Memory devices are JEDEC standard unbuffered  

DIMM modules, based on DDR2 SDRAM technology. 

These devices consist of CMOS DDR2 SDRAMs in FBGA  

packages on a 240-pin glass epoxy substrate.  

The memory array is designed with Double Data Rate  

(DDR2) Synchronous DRAMs for unbuffered applications. 

The pipelined, multibanked architecture of DDR2 SDRAM  

allows for concurrent operation, thereby providing high, effective bandwidth. 

Decoupling capacitors are mounted on the PCB board in parallel for each 

DDR2 SDRAM, which provides proper voltage supply impedance over the 

whole frequency range of operations, in accordance with JEDEC 

specifications. 

These modules feature Serial Presence Detect (SPD) based on a serial 

EEPROM device, using the 2-pin I2C protocol.
