DESCRIPTION:
   The fully buffered dual in-line memory module (FB-DIMM) is the next generation memory architecture to meet the growing memory requirement of servers and workstations. The IDT Advanced Memory Buffer (AMB) chip is the essential building block located on each FB-DIMM. The IDT AMB receives commands and data from the host controller to control and write/read data to/ from the DRAMs on the DIMM. Commands and write data are sent southbound from the host controller to AMBs in a daisy chain fashion and interpreted by the target AMB. 

FEATURES:
• Advanced Memory Buffer for Fully buffered DIMMs
• 3.2 and 4 Gbit/s serial speeds (DDR2-533 and 667 DRAM)
• Support for up to eight DIMMs per channel
• Repeater Mode for extending FB-DIMM links
• Northbound and Southbound single lane fail over and channel
   error detection
• Voltage and Timing margin high-speed I/O test capability
• Fully Supports the FB-DIMM configuration register set
