The engine uses respective bit lines of the nonvolatile memory array as respective matching lines for searching. Respective memory strings (e.g., NAND memory strings) of the nonvolatile memory array are usable to store respective data words, e.g., corresponding to features to search for. Respective pluralities of the memory strings are coupled in parallel to respective shared bit lines. Various encodings of features and searches enable exact, approximate, and range matching. The engine has applicability to comparing and sorting, in addition to searching in application areas such as artificial intelligence (AI) and big data.

Abstract

A system based on computational memory and memory systems, such as embodied in computational solid state drive (SSD) technology, as described herein, reduces processor utilization and/or bus bandwidth utilization. The system is enabled to perform computational techniques (e.g., searching, computing, and/or accessing) using resources of the computational SSDs, rather than processor and/or bus resources, thus reducing or minimizing information movement between processing elements and storage devices. Computational SSD technology enables managing, organizing, selecting, and analyzing ever increasing data volume in real time. A computational SSD is enabled to store and to operate on data locally, e.g., using resources of the computational SSD. Thus, processing, storage, and bandwidth requirements of a system are reduced by using the computational SSD.
