Assignee: nan
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A semiconductor device, comprising:
a stack of alternating oxide materials and conductive materials, one or more of the oxide materials of the stack comprising at least two portions of different densities;
discrete charge storage structures laterally adjacent to the conductive materials of the stack, the discrete charge storage structures comprising a uniform height across a length thereof and no portion of the conductive materials of the stack overlying or underlying the discrete charge storage structures, wherein a width of a portion of the at least two portions proximal to the conductive materials is less than a width of another portion of the at least two portions distal to the conductive materials;
a charge block material between the discrete charge storage structures and the respective laterally adjacent conductive materials of the stack; and
a pillar extending through the stack of alternating oxide materials and conductive materials.
