Features
240-pin JEDEC-compliant DIMM, 133.35 mm wide by 30 mm high
Operating Voltage: 1.5V ±0.075
I/O Type: SSTL_15
On-board I2C temperature sensor with integrated Serial PresenceDetect (SPD) EEPROM
Data Transfer Rate: 10.6 Gigabytes/sec
DTM64356A is a registered 2Gx72 memory module,
which conforms to JEDEC's DDR3, PC3-10600 standard.
The assembly is Dual-Rank. Each Rank is comprised of
eighteen Samsung 1Gbx4 DDR3-1333 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.
Data Bursts: 8 and burst chop 4 mode
ZQ Calibration for Output Driver and On-Die Termination (ODT)
Programmable ODT / Dynamic ODT during Writes
Programmable CAS Latency: 6, 7, 8 and 9
Bi-directional Differential Data Strobe signals
SDRAM Addressing (Row/Col/Bank): 16/11/3
Fully RoHS Compliant
