DTM68307A is a load reduced 4Gx72 memory module, which conforms to JEDEC's DDR4-2666, PC4-2666 standard. The assembly is Dual-Rank containing - eighteen Micron 2Gbx4 DDR4-2666 SDRAMs. One 4K-bit EEPROM is used for Serial Presence Detect and a Registering Clock Driver, with Address and Command Parity, is also used as well as data buffers to reduce the overall loading on the data bus. Both output driver strength and input termination impedance are programmable to maintain signal integrity on the I/O signals in a Fly-by topology. A thermal sensor accurately monitors the DIMM module and can prevent exceeding the maximum operating temperature of 95C.
