Claim Text:
1. A method of forming an array of cross point memory cells, comprising: forming elevationally inner multi-resistive state material elevationally over inner conductive electrode material; patterning the inner multi-resistive state material and the inner conductive electrode material to form spaced first lines individually comprising the inner multi-resistive state material elevationally over the inner conductive electrode material; forming elevationally outer multi-resistive state material elevationally over and electrically coupled to the inner multi-resistive state material of the first lines; patterning the outer multi-resistive state material to form spaced second lines that individually are elevationally over individual of the first lines, the second lines individually extending longitudinally along and individually being electrically coupled longitudinally along individual of the first lines; and forming spaced third lines comprising outer conductive electrode material crossing elevationally over and electrically coupled to the patterned outer multi-resistive state material.
