Abstract
A nonvolatile memory cell including at least two two-terminal non-linear steering elements arranged in series, and a resistivity switching storage element arranged in series with the at least two two-terminal non-linear steering elements. A memory array, comprising a plurality of the nonvolatile memory cells is also described. A method of forming a nonvolatile memory cell is also described.
Claims28
A memory array, comprising:
- a plurality of nonvolatile memory cells, wherein each of the plurality of memory cells comprises at least two two-terminal non-linear steering elements arranged in series and a resistivity switching storage element arranged in series with the at least two two-terminal non-linear steering elements;
- a plurality of word lines;
- and
- a plurality of bit lines,
- wherein the plurality of nonvolatile memory cells, word lines and bit lines are arranged to comprise a monolithic three dimensional memory array.
