Memory centric computational memory system

Abstract

A memory structure including three-dimensional NOR memory strings and method of fabrication is disclosed. In one embodiment, a memory system includes a set of memory modules of quasi-volatile memory circuits interconnected to a memory controller and having a set of memory ports. The memory system includes a first processor port, a second processor port, and one or more DIMM interface ports to be coupled to respective processors for providing access to the set of memory modules. In another embodiment, an artificial intelligence (AI) computing system includes a set of memory modules of quasi-volatile memory circuits interconnected to a memory controller and an arithmetic function block performing multiply and accumulate functionalities using data stored in the memory modules. The set of memory modules are accessed to perform read, write and erase memory operations in a rotating manner in each computing cycle.
