These Memory devices are JEDEC standard unbuffered DIMM modules,
based on CMOS 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 SDRAMs 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 featur Serial Presence Detect (SPD) based on a serial EEPROM device, using the 2-pin I2C protocol.
