Storage and Computing Unit and Chip

This application provides a unit, including a first transistor, a memristor, and a resistance modulation unit, where a first port of the resistance modulation unit and a first port of the memristor are connected to a first electrode of the first transistor, and the first electrode of the first transistor is configured to control the first transistor to be connected and disconnected; the resistance modulation unit is configured to adjust, based on a resistance of the memristor, a voltage applied to the first electrode of the first transistor; where the resistance of the memristor is used to indicate the first data stored by the memristor; and when a voltage used to indicate second data is input to a second electrode of the first transistor which is configured to output a computation result of the first data and the second data from a third electrode of the first transistor.
