Memory cells

A memory cell comprising:

• a data storage region between a pair of conductive structures;
• the data storage region comprising at least two physically different metal oxides and being configured to support a filament which provides resistive properties of the memory cell associated with a memory state;
• wherein the data storage region comprises two or more portions;
• with one of the portions supporting a higher resistance segment of said filament and another of the portions supporting a lower resistance segment of said filament;
• and
• wherein the lower resistance segment is directly against one of said surfaces.
