DTM64396E is an Unbuffered 1Gx72 memory module, which conforms to JEDEC's DDR3, PC3-12800 standard. The assembly is dual rank, with each rank containing nine Samsung 512Mx8 DDR3 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.
