DTM63371B is an Unbuffered non-ECC 128Mx64 memory module, which conforms to JEDEC's DDR2, PC2-6400 standard. The assembly is comprised of one Rank of eight 128Mx8 DDR2 Samsung SDRAMs. One 2K-bit EEPROM is used for Serial Presence Detect.

Both output driver strength and input termination impedance are programmable to maintain signal integrity on the I/O signals.
