Method and apparatus with memory management based on memory group

Abstract

An electronic device includes: a host processor configured to: generate a memory group allocated to an expanded virtual memory in response to receiving memory usage information; determine a target memory group comprising a page on which a page fault has occurred among memory groups allocated to the expanded virtual memory, based on the memory usage information; and migrate the target memory group from one of a host memory, an accelerator memory, and a storage device, which comprises the target memory group, to either one of the host memory and the accelerator memory in which the page fault has occurred; and an accelerator configured to perform an operation using the accelerator memory, wherein the expanded virtual memory is a virtual single address space using the host memory, the accelerator memory, and the storage device.

Dependencies are inferred from the claim text.
