Abstract

See full text

Some embodiments include methods in which a memory cell is formed to have programmable material between first and second access lines, with the programmable material having two compositionally different regions. A concentration of ions and/or ion-vacancies may be altered in at least one of the regions to change a memory state of the memory cell and to simultaneously form a pn diode. Some embodiments include memory cells having programmable material with two compositionally different regions, and having ions and/or ion-vacancies diffusible into at least one of the regions. The memory cell has a memory state in which the first and second regions are of opposite conductivity type relative to one another.
