MBIST and IBIST test functions
Transparent mode for DDR2 SDRAM test support
Full DIMM Heat Spreader
High-speed differential point-to-point link
Fully RoHS Compliant
The DTM65525B is a Dual Rank PC2-6400 Fully Buffered
256MX72 ECC DIMM that conforms to the JEDEC FB-DIMM
standard. Each rank is comprised of nine Hynix 128Mx8
DDR2 DRAMs. One IDT (Rev C1) Advanced Memory Buffer
(AMB) is used as the interface between the system memory
bus and DIMM DRAMs. One 2K-bit EEPROM is used for
Serial Presence Detect. For improved thermal performance,
a Full DIMM Heat Spreader with thermal interface material
(TIM) is attached to the front and back of the DIMM.
