Abstract

An array of cross point memory cells comprises spaced first lines which cross spaced second lines. Two memory cells are individually between one of two immediately adjacent of the second lines and a same single one of the first lines.

Claims (13)

1. An array of cross point memory cells comprising spaced first lines which cross spaced second lines, two memory cells individually between one of two immediately adjacent of the second lines and a same single one of the first lines, each of the two memory cells individually comprising a single one and only one select device, a same single one select device for and that is shared by every two immediately adjacent of said memory cells, the two memory cells sharing a single first electrode and having non-shared second electrodes, the first electrode being a conductive pillar electrode.

2. The array of claim 1 wherein the two immediately adjacent memory cells each comprise programmable material, the same single shared select device being directly electrically coupled to the one first line and being directly electrically coupled to the programmable material of each of the two immediately adjacent memory cells.

3. An array of cross point memory cells comprising:

spaced first lines which cross spaced second lines; and

two memory cells individually between one of two immediately laterally adjacent of the second lines and a same single one of the first lines, the two memory cells being individually elevationally elongated and sharing an elevationally elongated conductive pillar electrode, the shared elevationally elongated conductive pillar electrode being electrically coupled to the same single one respective first line at a single one longitudinal location along the respective same single one first line on the same side of the respective same single one first line.

4. The array of claim 3 wherein the same side is a top side of the respective same single one first line.

5. The array of claim 3 wherein the shared elevationally elongated conductive pillar is directly electrically coupled to the respective same single one first line.

6. The array of claim 5 wherein the memory cells individually comprise a select device.

7. The array of claim 5 wherein the same side is a top side of the respective same single one first line.

8. The array of claim 3 wherein the memory cells individually comprise a select device, the shared elevationally elongated conductive pillar being electrically coupled to the respective same single one first line through the select device.

9. The array of claim 8 wherein the same side is a top side of the respective same single one first line.

10. The array of claim 8 wherein the shared elevationally elongated conductive pillar is directly electrically coupled to the select device and the select device is directly electrically coupled to the respective same single one first line.

11. The array of claim 10 wherein the same side is a top side of the respective same single one first line.
