Method for migrating memory data, related apparatus, and computer device

A memory, comprising:

• at least one non-transitory storage medium;
• and
• a controller;
• wherein the at least one storage medium stores computer instructions thereon, wherein the at least one non-transitory storage medium and the computer instructions are configured, with the controller, to cause the memory to at least:
• obtain a sampling result by sampling obtained access requests according to a sampling rule, wherein the access request indicates an operation performed by an application run by a processor in a computer device on a memory medium, and wherein the sampling rule indicates a periodic sampling mode;
• collect statistics on access frequencies of pages indicated by the sampling result, wherein the access frequencies of the pages are used to determine access temperatures of the pages;
• and
• trigger migration of memory data between at least two memory media of different types based on the access frequencies.

A computer device comprising:

• a plurality of memory media of different types;
• at least one processor, wherein the processor is associated with at least two memory media of different types;
• and
• at least one non-transitory storage, having computer instructions stored thereon, wherein the at least one non-transitory storage and the computer instructions are configured, with the at least one processor, to cause the computer device to at least:
• sample obtained access requests according to a sampling rule, to obtain a sampling result, wherein the access request indicates an operation performed by an application run by a processor in a computer device on a memory medium, and wherein the sampling rule indicates a periodic sampling mode;
• collect statistics on access frequencies of pages indicated by the sampling result, wherein the access frequencies of the pages are used to determine access temperatures of the pages;
• and
• trigger migration of memory data between the at least two memory media of different types based on the access frequencies.
