P1-P3P4-P6P7-P9P10-P11
DDR2 SDRAM FBDIMM
MT18HTF12872FDZ – 1GB
MT18HTF25672FDZ – 2GB
Features
• 240-pin, DDR2 fully buffered dual in-line memory
module (FBDIMM)
• Fast data transfer rates: PC2-4200, PC2-5300, or
PC2-6400
• 1GB (128 Meg x 72), 2GB (256 Meg x 72)
• 3.2 Gb/s, 4 Gb/s, or 4.8 Gb/s link transfer rates
• High-speed, 1.5V differential, point-to-point link be-
tween the 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 FBDIMM devi-
ces per channel
• SMBus interface to AMB for configuration register
access
• In-band and out-of-band command access
• Deterministic protocol
– Enables memory controller to optimize DRAM ac-
cesses for maximum performance
– Delivers precise control and repeatable memory
behavior
• Automatic DDR2 SDRAM bus and channel calibra-
tion
• Transmitter de-emphasis to reduce ISI
