Publication number: 20210043644Abstract: A method used in forming a memory array comprising strings of memory cells and operative through-array-vias (TAVs) comprises forming a stack comprising vertically-alternating insulative tiers and conductive tiers. The stack comprises a TAV region and an operative memory-cell-string region. The TAV region comprises spaced operative TAV areas. Operative channel-material strings are formed in the stack in the operative memory-cell-string region and dummy channel-material strings are formed in the stack in the TAV region laterally outside of and not within the operative TAV areas. Operative TAVs are formed in individual of the spaced operative TAV areas in the TAV region. Other methods and structure independent of method are disclosed.Type: ApplicationFiled: August 5, 2019Publication date: February 11, 2021Applicant: Micron Technology, Inc.Inventors: Yi Hu, Merri L. Carlson, Anilkumar Chandolu, Indra V. Chary, David Daycock, Harsh Narendrakumar Jain, Matthew J. King, Jian Li, Brett D. Lowe, Prakash Rau Mokhna Rau, Lifang Xu

Publication number: 20210013221Abstract: A method used in forming a memory array comprising strings of memory cells and operative through-array-vias (TAVs) comprises forming a stack comprising vertically-alternating insulative tiers and conductive tiers. The stack comprises a TAV region and an operative memory-cell-string region. Operative channel-material strings are formed in the stack in the operative memory-cell-string region and dummy channel-material strings are formed in the stack in the TAV region. At least a majority of channel material of the dummy channel-material strings is replaced in the TAV region with insulator material and operative TAVs are formed in the TAV region. Other methods and structures independent of method are disclosed.Type: ApplicationFiled: July 10, 2019Publication date: January 14, 2021Applicant: Micron Technology, Inc.Inventors: David Daycock, Prakash Rau Mokhna Rau

Patent number: 10586801Abstract: 3D NAND memory cells can include a source layer, a dielectric layer disposed on the source layer, and a select gate source (SGS) layer disposed on the dielectric layer. A plurality of alternating layers of conducting material and insulating material can be disposed on the SGS layer. A conductive channel can be formed within a cell pillar trench. The conductive channel can be in contact with the source layer and the plurality of alternating layers. The cell pillar trench can be positioned in a substantially perpendicular orientation with respect to the plurality of alternating layers.Type: GrantFiled: January 12, 2018Date of Patent: March 10, 2020Assignee: Intel CorporationInventors: Prakash Rau Mokhna Rau, Wesly McKinsey, Rithu Bhonsle

Publication number: 20190294330Abstract: Solid state memory technology is disclosed. In one example, a solid state memory component can include a plurality of bit lines, a source line, and a plurality of non-functional memory pillars. Each non-functional memory pillar is electrically isolated from one or both of the plurality of bit lines and the source line. In another example, a solid state memory component can include a plurality of pillars located in a periphery portion of the solid state memory component, and memory cells adjacent to each of the pillars. Associated systems and methods are also disclosed.Type: ApplicationFiled: June 11, 2019Publication date: September 26, 2019Applicant: Intel CorporationInventors: Jun Zhao, Gowrisankar Damarla, David A. Daycock, Gordon A. Haller, Sri Sai Sivakumar Vegunta, John B. Matovu, Matthew R. Park, Prakash Rau Mokhna Rau
