Abstract

The present memory device includes first and second electrodes, a passive layer between the first and second electrodes and an active layer between the first and second electrodes, the active layer being of a material containing randomly oriented pores which are interconnected to form passages through the active layer.

Claims (26)

1 . A memory device comprising:

first and second electrodes;

a passive layer between the first and second electrodes; and

an active layer between the first and second electrodes, the active layer comprising material containing pores which are interconnected.

2 . The memory device of claim 1 wherein the pores are randomly oriented.

3 . The memory structure of claim 2 wherein the interconnected pores provide passages through the active layer.

4 . The memory device of claim 3 wherein the active layer comprises organic material.

5 . The memory device of claim 3 wherein the passive layer comprises copper sulfide.

6 . The memory device of claim 3 wherein the active layer comprises spin-on material.

7 . The memory device of claim 3 wherein the active layer is a polymer.

8 . The memory device of claim 7 wherein the active layer is a methylated siloxane polymer.

9 . The memory device of claim 7 wherein the active layer is a siloxane spin-on glass.

10 . The memory device of claim 7 wherein the active layer is methyl silsequioxane (MSQ).

11 . A method of fabricating a memory device comprising:

providing a first electrode;

providing a passive layer on the first electrode;

providing an active layer on the passive layer, the active layer containing interconnected pores; and

providing a second electrode on the active layer.

12 . The method of claim 11 wherein the pores are randomly oriented.

13 . The method of claim 12 wherein the interconnected pores provide passages through the active layer.

14 . The method of claim 13 wherein the active layer is spun onto the passive layer.

15 . The method of claim 13 wherein the active layer comprises organic material.

16 . The method of claim 15 wherein the active layer is a polymer.

17 . The method of claim 16 wherein the active layer is a methylated siloxane polymer.

18 . The memory device of claim 16 wherein the active layer is a siloxane spin-on glass.

19 . The memory device of claim 16 wherein the active layer is methyl silsequioxane (MSQ).
