Abstract

The invention discloses a memory control method and device, which are used for improving the storage speed of the memory. The memory is provided with a first storage area and a second storage area, the storage speed of the first storage area is higher than that of the second storage area, and the method comprises the steps that under the condition that the equipment is about to enter a second state from a first state, establishing connection between the memory and a boot system in the equipment, wherein the power consumption of the second state is lower than that of the first state, and the booting system is used for booting the starting of the equipment operating system; migrating the data of the first storage area to a second storage area based on the boot system. By adopting the scheme provided by the invention, the situation that the storage speed of the memory is slowed down due to the fact that the storage area with the highest storage speed is fully written is reduced, and the storage speed of the memory is improved.

Description

technical field [0001] The present application relates to the field of computers, in particular to a memory control method and device. Background technique [0002] Setting storage areas with different storage speeds in the storage area has become a development trend in the storage field, such as SSD (Solid State Drive, solid state drive), which is a passive device, and there will be SLC (Single-Level Cell, single-layer Memory), MLC (Multi-Level Cell, double-layer memory) and TLC (Trinary-Level Cell, three-layer memory) and other different storage area designs, the storage speed of different storage areas is different, due to the storage space of each storage area Limited, especially SLC with the fastest storage speed, its storage space is more precious, while for storage like SSD, the background clearing task should be executed in its idle state. [0003] In the prior art, in order to reduce the power consumption of the whole machine, the operating system will allow the me...
