Description
Features
240-pin JEDEC-compliant DIMM, 133.35 mm wide by 30 mm high
Operating Voltage: 1.5 V ±0.075 V, I/O Type: SSTL_15
2
On-board I C temperature sensor with integrated Serial PresenceDetect (SPD) EEPROM
Data Transfer Rate: 10.6 Gigabytes/sec
Data Bursts: 8 and burst chop 4 mode
ZQ Calibration for Output Driver and On-Die Termination (ODT)
Programmable ODT / Dynamic ODT during Writes
DTM64314D is an Unbuffered 512Mx72
memory module, which conforms to
JEDEC's DDR3, PC3-10600 standard. The
assembly is Dual-Rank. Each Rank is
comprised of nine 256Mx8 DDR3-1333
Hynix SDRAMs. One 2K-bit EEPROM is
used for Serial Presence Detect.
A thermal sensor accurately monitors the
DIMM module and can prevent exceeding
the maximum operating temperature of 95C.
Both output driver strength and input
termination impedance are programmable to
maintain signal integrity on the I/O signals.
Programmable CAS Latency: 6, 7, 8, and 9
Differential Data Strobe signals
SDRAM Addressing (Row/Col/Bank): 15/10/3
Fully RoHS Compliant
