Abstract
A high bandwidth non-volatile memory (NVM) is described suitable for providing neural network weight data to an AI accelerator processing core or cores. An artificial intelligence (AI) inference memory device employing the high bandwidth NVM technology as described herein can comprise a logic layer die including channel logic implementing connections between a plurality of channels for conducting data to and from an accelerator core via a bus and a plurality of non-volatile memory (NVM) dies stacked vertically one above another, forming a layered vertical stack of NVM dies, each of the NVM dies including at least one memory chip and a plurality of direct vertical connections to a corresponding channel in the logic layer.
