  • Patent number: 9019771
    Abstract: A memory cell array of dielectric charge trapping memory cells and method for performing program, read and erase operations on the memory cell array that includes bits stored at charge trapping sites in adjacent memory cells. A bit of information is stored at a first charge trapping site in a first memory cell and a second charge trapping site in a second adjacent memory cell. Storing charge at two trapping sites in adjacent memory cells increases data retention rates of the array of memory cells as each charge trapping site can be read to represent the data that is stored at the data site. Each corresponding charge trapping site can be read independently and in parallel so that the results can be compared to determine the data value that is stored at the data site in an array of dielectric charge trapping memory cells.

  • Patent number: 8962466
    Abstract: A metal oxide formed by in situ oxidation assisted by radiation induced photo-acid is described. The method includes depositing a photosensitive material over a metal surface of an electrode. Upon exposure to radiation (for example ultraviolet light), a component, such as a photo-acid generator, of the photosensitive material forms an oxidizing reactant, such as a photo acid, which causes oxidation of the metal at the metal surface. As a result of the oxidation, a layer of metal oxide is formed. The photosensitive material can then be removed, and subsequent elements of the component can be formed in contact with the metal oxide layer. The metal oxide can be a transition metal oxide by oxidation of a transition metal. The metal oxide layer can be applied as a memory element in a programmable resistance memory cell. The metal oxide can be an element of a programmable metallization cell.
