The IDT Advanced Memory Buffer (AMB) chip is the essential building block located on each FB-DIMM. The IDT AMB receives mands and data from the host controller to control and write/read data to/ from the DRAMs on the DIMM. mands and write data are sent southbound from the host controller to AMBs in a daisy chain fashion and interpreted by the target AMB. Status and read data are sent northbound from AMBs to the host controller also in a daisy chain fashion, passing through non-target AMBs. This unique channel structure alleviates buffer loading issues mon in registered DIMM technology, enabling designers to use a large number of DIMMs within a single system. IDTAMB0480 plies with the latest JEDEC defined FB-DIMM Architecture and Protocol Specification and supports DDR2-533 and DDR2-667 DRAM. It also enables serial data transfer at 3.2 and 4.0Gbps. The IDTAMB0480 supports servers, workstations, storage devices and munication applications that support the next generation FB-DIMM architecture. - - EXPANDED FEATURES : - - - - - - Wide range DDR Timing Control Superfine adjustment for DDR timing...
