Description 
DTM68300A is a load reduced 4Gx72 
memory module, which conforms to 
JEDEC's DDR4-2133, PC4-2133 standard. 
The assembly is Quad-Rank. Ranks are 
comprised of Samsung 2Gbx4 DDR4-2133 
DDP 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.
