Abstract
A non-volatile 3D memory search architecture provides for receiving searches for application to select lines and word lines of a non-volatile 3D memory array. The architecture uses two word lines per unit of information of the searches and two memory devices per unit of stored feature to search against. The architecture uses respective bit lines of the non-volatile 3D memory array as respective matching lines for searching. Respective memory strings (e.g., NAND memory strings) of the non-volatile 3D memory array are usable to store respective data values, e.g., corresponding to elements to search for. Respective pluralities of the memory strings are coupled in parallel to respective shared bit lines. The architecture has applicability to comparing and sorting, in addition to searching in application areas such as artificial intelligence (AI) and big data.
