Resistance variable memory apparatus

摘要

A resistance variable memory apparatus (100) of the present invention includes a current suppressing element (116) which is connected in series with each resistance variable layer (114) and whose threshold voltage is VF, and is configured to apply a first voltage V1 to a first wire (WL) associated with a selected nonvolatile memory element, apply a second voltage V2 to a second wire (BL) associated with the selected nonvolatile memory element, apply a third voltage V3 to a first wire (WL) which is not associated with the selected nonvolatile memory element and apply a fourth voltage V4 to a second wire (BL) which is not associated with the selected memory element when writing data or reading data, wherein V2≦̸V3
