Description
240-pin JEDEC-compliant DIMM, 133.35mm wide by 30mm
high
high
Operating Voltage: 1.8 V ±0.1
I/O Type: SSTL_18
Data Transfer Rate: 6.4 Gigabytes/sec
Data Bursts: 4 or 8 bits, Sequential or Interleaved ordering
Programmable I/O driver strength (OCD)
Programmable On-Die Termination (ODT)
Programmable CAS Latency: 4 or 5
Differential/Redundant Data Strobe signals
SDRAM Addressing (Row/Col/Bank): 14/10/3
Fully RoHS Compliant
DTM63393C is an Unbuffered 128Mx72 memory
module, which conforms to JEDEC's PC2-6400
standard. The DIMM has one Rank, comprised of
nine 128Mx8 DDR2 Samsung SDRAMs. One 2K-
bit EEPROM is used for Serial Presence Detect.
Both output driver strength and input termination
impedance are programmable to maintain signal
integrity on the I/O signals.
The Data Strobe signals may be used either as
differential pairs, or as single-ended strobes with
the /DQS signals disabled.
Data Mask inputs are provided to selectively
prevent data from being written to an 8-bit byte.
Alternatively, these may be used as Redundant
Data Strobes for use in systems with a mix of x4
and x8 DRAMs.
