State of the Art CK CMD DATA 4 • Today’s DDR2 modules perform at 800 MT/s over a 72 bit data bus and 400 MT/s over a 26 bit command bus • DDR3 modules (2006) perform at twice DDR2 speeds • FB-DIMM 14-bit 4.8GHz differential bus 9.6GHz • All must be implemented using standard grade PCB materials and low cost edge connector technology
