Title:
GARBAGE COLLECTION METHOD, AND MEMORY AND MEMORY MANAGEMENT APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/082252
Kind Code:
A1
Abstract:
A garbage collection method, and a memory and a memory management apparatus. In the method, a memory controller can receive first garbage collection (GC) information from a processor by means of an information management interface, and map a first logic storage area in the first GC information into a first physical storage area; and the memory controller determines a plurality of second physical storage areas, on which the memory controller needs to execute a second GC operation, and when the first physical storage area has intersections with a plurality of second physical storage areas, selects a first target physical storage area from among the second physical storage areas, which have intersections with the first physical storage area. In this way, the influence, on the execution of the second GC operation by the memory controller, of the execution of the first GC operation on the first logic storage area by the processor is reduced, that is, the workload of the memory controller ineffectively transferring valid data when the second GC operation is subsequently executed can be reduced, thereby improving the efficiency of the memory controller executing the second GC operation, and ensuring the performance of the memory.
