- DDRIII Logic is a 1.5V supply-referenced IO interface for digital integrated circuits. It is particularly intended to improve operation in situations where buses must be isolated from relatively large stubs, as defined by the JESD79-3A standard. Calibrated On Die Termination (ODT) eliminates external component cost and provides optimum far-end termination, improving signal integrity. A default-calibrated driver in the full-strength mode results in an output impedance value of 34Ω or 40Ω Ω. DDRIII is intended to be technology-independent for different multi-drop bus and point-to-point applications, which addresses system cost structures and required performance levels.
