Patent ID: 7038485

Claim:
A device, comprising: a terminating resistor circuit having a plurality of resistor elements, each of said resistor elements having a control node and being activated to represent a predetermined resistance value when the control node takes an active level; and a selection circuit having a set of output nodes each connected to the control node of an associated one of said resistor elements, a first input node supplied in series with first selection data, a set of second input nodes supplied in parallel respectively with second selection data, and a mode node supplied with a mode signal, said selection circuit responding to said first selection data supplied in series to said first input node and producing a set of selection signals at said set of output nodes when said mode signal takes a first level, said selection circuit responding to said second selection data supplied in parallel to said set of second input nodes and producing the set of selection signals at said set of output nodes when said mode signal takes a second level.
