Storage array, and storage chip and method for storing logical relationship of objects

A storage array, characterized in that the storage array at least comprises:

• first leading-out wires and second leading-out wires which have the same quantity and are respectively located in a line direction and a column direction;
• the first leading-out wires and the second leading-out wires being respectively numbered;
• a storage unit being connected between each first leading-out wire and each second leading-out wire having different serial numbers;
• and a controllable switch being connected between each first leading-out wire and each second leading-out wire having a same serial number, wherein,
• the storage unit comprises a variable-resistance two-terminal device and a gating diode which are connected in series, and the gating diode is forwardly conducted from the first leading-out wire to the second leading-out wire and is reversely cut off from the second leading-out wire to the first leading-out wire;
• and
• the controllable switch is switched between a bidirectional cut-off state and a unidirectional conducted state from the second leading-out wire to the first leading-out wire.
