Abstract

Non-volatile storage devices having reversible resistance storage elements are disclosed herein. In one aspect, a memory cell unit includes one or more memory cells and a transistor (e.g., FET) that is used to control (e.g., limit) current of the memory cells. The drain of the transistor may be connected to a first end of the memory cell. If the memory cell unit has multiple memory cells then the drain may be connected to a node that is common to a first end of each of the memory cells. The source of the transistor is connected to a common source line. The gate of the transistor may be connected to a word line. The same word line may connect to the transistor gate of several (or many) different memory cell units. A second end of the memory cell is connected to a bit line.
