DTM64309C

4GB - 240-Pin 4Rx8 Registered ECC DDR3 DIMM

Features

Description

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 presence-

detect (SPD) EEPROM

Data Transfer Rate: 8.5 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

Programmable CAS Latency: 6, 7, and 8

Bi-Directional Differential Data Strobe signals

SDRAM Addressing (Row/Col/Bank): 14/10/3

Fully RoHS Compliant

DTM64309C is a registered 512Mx72 memory

module, which conforms to JEDEC's DDR3,

PC3-8500 standard. The assembly is Quad-

Rank. Each Rank is comprised of nine

128Mx8 DDR3 Hynix 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.

A Heat Spreader is attached to improve the

thermal characteristics of the module.
