US Patent 11475947 Decoding architecture for memory tiles

Methods, systems, and devices for decoding architecture for memory tiles are described. Word line tiles of a memory array may each include multiple word line plates, which may each include a sheet of conductive material that includes a first portion extending in a first direction within a plane along with multiple fingers extending in a second direction within the plane. A pillar tile may include one or more pillars that extend vertically between the word line plate fingers. Memory cells may each be couple with a respective word line plate finger and a respective pillar. Word line decoding circuitry, pillar decoding circuitry, or both, may be located beneath the memory array and in some cases may be shared between adjacent pillar tiles.
