The TS256MFB72V8U-T is a 256M x 72bits ECC DDR2-800 fully buffered DIMM. The TS256MFB72V8U-T consists of 18PCs 128M x 8bits DDR2 SDRAMs in 68 ball FBGA package, 1 PC 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 controls for the DRAM reside 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.
