A storage array (1), and a storage chip and method for storing logical relationship of objects. The storage array (1) comprises: first outgoing lines (L0-Ln) and second outgoing lines (C0-Cn), wherein a storage unit (11) is respectively connected between each first outgoing line (L0-Ln) and each second outgoing line (C0-Cn) that have different numbers, and a controllable switch (M) is respectively connected between each first outgoing line (L0-Ln) and each second outgoing line (C0-Cn) that have the same number. The storage chip comprises: an interface module (2); a control module (3) for generating a control signal; a driving module (4) for generating write current, erase current or read current; a first decoder (5) for gating the first outgoing lines (L0-Ln) and a second decoder (6) for gating the second outgoing lines (C0-Cn); and the storage array (1) for storing a logical relationship value. The storage method comprises write and read operations. The storage of a logical relationship among objects is impl
