Abstract: Embodiments of this application provide a memory management method, a memory management apparatus, and an electronic device. The memory management method includes: receiving a first input of a user, where the first input is used to enable a first application to enter a background state; blocking an interface related to access to a buffer in a first buffer set, where the buffer in the first buffer set belongs to a buffer related to decoding of a first video played by the first application; and reclaiming physical memory corresponding to the buffer in the first buffer set. According to the memory management method, the memory management apparatus, and the electronic device provided in embodiments of this application, physical memory corresponding to a buffer related to video decoding can be reclaimed, so that available physical memory of an entire system is increased.

Abstract: Embodiments of this application provide a memory processing method, an electronic device, and a readable storage medium. In the method, in a scenario in which an application program and a hardware device share a first physical memory, when the application program is switched to a background, the application program sends a first command to a memory processing apparatus, where the first command indicates to release the first physical memory of the application program; and the memory processing apparatus releases the first physical memory in response to the first command. In embodiments of this application, when the application program is switched to the background, and temporarily does not need to use the first physical memory, the application program may actively request to release the first physical memory, to increase an available memory of an electronic device.

Abstract: The present application provides a negative electrode plate, a preparation method therefor, a secondary battery and a power consuming device. The method comprises: providing a negative electrode current collector; coating at least one surface of the negative electrode current collector with a photosensitive adhesive and curing same to form a photosensitive layer; patterning light into a preset pattern, and allowing the incidence of the light from the surface of the photosensitive layer that is away from the negative electrode current collector to the photosensitive layer to expose the photosensitive layer; developing the exposed photosensitive layer to obtain a photosensitive layer having a recessed portion; filling the recessed portion with a negative electrode slurry, and curing the negative electrode slurry to form a negative electrode film layer; and removing at least a part of the photosensitive layer to obtain the negative electrode plate.
