Memory management method and apparatus

Abstract

A memory management method and apparatus are provided, relating to the field of storage technology. The method is executed by a first device in a storage system, the first device supporting a page table with a first bit width, and a second device supporting a page table with a second bit width. The first device requests memory based on a first segment registration request, obtaining a first virtual address space. If the first virtual address space exceeds the first bit width, the first segment is split into a second segment and a third segment. The second and third segments are contiguous when memory addressing is performed based on the second bit width page table. Page table registration is performed on the second and third segments respectively. This adds processing logic for the first device on the first bit width virtual address, mapping the first bit width virtual address to the second bit width virtual address, enabling the second device to process the first bit width virtual address, thus solving the problem of page table incompatibility between devices with different architectures.
