A memory device with unipolar and bipolar selectors

摘要

A memory device is proposed. The memory device includes a plurality of memory cells (P,S), wherein each memory cell includes a storage element (P) and a selector (S) for selecting the corresponding storage element during a reading operation or a programming operation. The selector includes a unipolar element (M) and a bipolar element (D;B). The memory device further includes control means (110s) for prevalently enabling the unipolar element during the reading operation or the bipolar element during the programming operation.
