DTM68149-M is a registered 1Gx72 memory module, which conforms to JEDEC's PC4-2933Y standard. The assembly is Single-Rank with the rank containing eighteen Micron 2Gbx4 DDR4- 2933Y SDRAMs. One 2K-bit EEPROM is used for Serial Presence Detect and a combination register/PLL, with Address and Command Parity, is also used.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.
