DDR2 SDRAM FBDIMM
MT18HTF12872F – 1GB
MT18HTF25672F – 2GB
For the latest data sheets and technical notes, refer to Micron’s Web site: www.micron.com
Features
• 240-pin, DDR2 fully buffered dual in-line memory
module (FBDIMM)
• Fast data transfer rates: PC2-4200, PC2-5300, and
PC2-6400
• 1GB (128 Meg x 72), 2GB (256 Meg x 72)
• 3.2 Gb/s, 4.0 Gb/s, and 4.8 Gb/s link transfer rates
• High-speed, differential, point-to-point link
between host controller and advanced memory
buffer (AMB)
• Fault-tolerant; can work around a bad bit lane in
each direction
• High-density scaling with up to eight FBDIMMs per
channel
• SMBus interface to AMB for configuration register
access
• In-band and out-of-band command access
• Deterministic protocol
– Enables memory controller optimization of DRAM
accesses for maximum performance
– Delivers precise control and repeatable memory
behavior
•Automatic DDR2 SDRAM bus and channel
calibration
• Transmitter de-emphasis to reduce ISI
• MBIST and IBIST test functions
• Transparent mode for DRAM test support
•V
DD = VDDQ = +1.8V for DDR2 SDRAM
•V
REF = 0.9V SDRAM command and address
termination
•V
CC = 1.5V for AMB
•V
DDSPD = +3.0V to +3.6V for AMB and EEPROM
• Serial presence-detect (SPD) with EEPROM
• Gold edge contacts
• Single rank
