摘要: A variable resistance memory array, programming a variable resistance memory element and methods of forming the array. A variable resistance memory array is formed with a plurality of word line transistors surrounding each phase change memory element. To program a selected variable resistance memory element, all of the bitlines are grounded or biased at the same voltage. A top electrode select line that is in contact with the selected variable resistance memory element is selected. The word line having the word line transistors surrounding the selected variable resistance memory element are turned on to supply programming current to the element. Current flows from the selected top electrode select line through the variable resistance memory element into the common source/drain region of the surrounding word line transistors, across the transistors to the nearest bitline contacts. The word lines are patterned in various lattice configurations.

摘要: A method of forming a silicon-containing dielectric material. The method includes forming a plasma comprising nitrogen radicals, absorbing the nitrogen radicals onto a substrate, and exposing the substrate to a silicon-containing precursor in a non-plasma environment to form monolayers of a silicon-containing dielectric material on the substrate. Additional methods are also described, as are semiconductor device structures including the silicon-containing dielectric material and methods of forming the semiconductor device structures.

摘要: A method of forming an array of memory cells includes forming lines of covering material that are elevationally over and along lines of spaced sense line contacts. Longitudinal orientation of the lines of covering material is used in forming lines comprising programmable material and outer electrode material that are between and along the lines of covering material. The covering material is removed over the spaced sense line contacts and the spaced sense line contacts are exposed. Access lines are formed. Sense lines are formed that are electrically coupled to the spaced sense line contacts. The sense lines are angled relative to the lines of spaced sense line contacts and relative to the access lines. Other embodiments, including structure independent of method, are disclosed.

摘要: Memory devices and methods for fabricating memory devices have been disclosed. One such method includes forming the memory stack out of a plurality of elements. An adhesion species is formed on at least one sidewall of the memory stack wherein the adhesion species has a gradient structure that results in the adhesion species intermixing with an element of the memory stack to terminate unsatisfied atomic bonds of the element. The gradient structure further comprises a film of the adhesion species on an outer surface of the at least one sidewall. A dielectric material is implanted into the film of the adhesion species to form a sidewall liner.
