Features Description
240-pin JEDEC-compliant DIMM, 133.35 mm wide by 30 mm high
Operating Voltage: VDD = VDDQ = +1.35V (1.283V to 1.45V)
Backward-compatible to VDD = VDDQ = +1.5V ±0.075V
On-board I2C temperature sensor with integrated serial presence-detect
(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
Programmable CAS Latency: 6, 7, 8, and 9
Bi-Directional Differential Data Strobe signals
SDRAM Addressing (Row/Col/Bank): 14/10/3
DTM64332B is a registered 256Mx72 memory
module, which conforms to JEDEC's DDR3L,
PC3L-10600 standard. The assembly is Dual-
Rank. Each Rank is comprised of nine 128Mx8
DDR3 Samsung 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.
Fully RoHS Compliant
