Abstract
A high-level architecture for 3D-NAND based in-memory search provides for receiving searches for application to select lines and word lines of a non-volatile 3D memory array. A search word is presented to a 3D-NAND memory along a direction of a bit line of the 3D-NAND memory. Each character of the word comprises a number of digits. Each digit is matched against respective layers of the 3D-NAND memory. Each digit is usable to represent one of a plurality of levels according to a selected encoding. Optionally, various lengths of words are accommodated via serial and/or parallel operations of one or more 3D-NAND memories.
