3. TS256MFB72V8U T Description The TS256MFB72V8U T is a 256M x 72bits ECC DDR2 800 Fully Buffered DIMM The TS256MFB72V8U T consists of 18pcs 128Mx8bits DDR2 SDRAMs in 68 ball FBGA package 1 pcs AMB IC and a 2048 bits serial EEPROM on a 240 pin printed circuit board The TS256MFB72V8U T is a 240pin fully buffered dual in line memory module The Advanced Memory Buffer also allows buffering of memory traffic to support large memory capacities All memory control for the DRAM resides in the host including memory request initiation timing refresh scrubbing sparing configuration access and power management The Advanced Memory Buffer interface is responsible for handling channel and memory requests to and from the local DIMM and for forwarding requests to other DIMMs on the memory channel Fully Buffered DIMM provides a high memory bandwidth large capacity channel solution that has a narrow host interface Features e 240pin fully buffered dual in line memory module e 3 2Gb s 4 0Gb s 4 8Gb s link transfer rate e 1 8V 0 1V Power Supply for DRAM VDD VDDQ 1 5V 0 075V Power Supply for AMB VCC e 3 3V 0 3V Power Supply for VDDSPD e Buffer Interface with high speed differential point to point Link at 1 5 volt e Channel error detection amp reporting e Channel fail over mode support e Serial presence detect with EEPROM e 8Banks e Posted CAS e Programmable CAS Latency 3 4 5 e Autom
