Abstract
A resistor switching circuit, a storage circuit and a consumable chip. The resistor switching circuit is used in the consumable chip, and includes a plurality of resistor switching branch circuits, the resistor switching branch circuit including a switching switch and a resistor, the switching switch and the resistor being connected in series in a conducting loop of a signal wire; and a decoder, connected to a data storage module in the consumable chip, and used for generating a switching instruction according to a signal output by the data storage module to control a switching switch of a corresponding resistor switching branch circuit to put a corresponding resistor into the conducting loop of the signal wire, so as to change a resistance value of the conducting loop of the signal wire.
