Embodiment Construction

[0066] In the data usage control method, device, and electronic device of the embodiments of the present invention, by controlling the current mapping table, users can conveniently access previously saved data, providing users with convenient and flexible data usage control.

[0067] The data usage control method of the embodiment of the present invention is used in a storage device that provides access services based on the mapping of logical addresses and physical addresses, such as figure 1 As shown, the data usage control method includes:

[0068] Step 11, interacting with the electronic device to obtain a pre-saved historical mapping table, the historical mapping table records the mapping relationship between the logical address and the physical address of the first physical storage area in the storage device;

[0069] Step 12, setting the historical mapping table as the currently used mapping table, so that the electronic device can access the first physical storage area...

Abstract

The invention discloses a data usage control method, device and storage device. The data usage control method is used in a storage device that provides access services based on the mapping of logical addresses and physical addresses, including: interacting with electronic devices, obtaining a pre-saved A historical mapping table, the historical mapping table records the mapping relationship between the logical address and the physical address of the first physical storage area in the storage device; the mapping table is set as the currently used mapping table, so that all The electronic device can access and operate the first physical storage area based on the mapping table. The invention provides a convenient and flexible control method for the data use of the digital storage device.

Description

technical field [0001] The invention belongs to the field of electronics, and in particular relates to a data usage control method, device and storage device. Background technique [0002] At present, there are a large number of digital storage devices that are different from traditional mechanical storage devices (such as hard disks, CDs, etc. based on optical drive heads for data storage), such as SSD hard disks. These digital storage devices provide access services based on the mapping of logical addresses and physical addresses. They provide logical addresses to external electronic devices for access, and internally realize the conversion of logical addresses and physical addresses through the mapping of logical addresses and physical addresses, and then provide physical addresses. The actual data access service within the address. [0003] However, the prior art does not provide a convenient and flexible control method for the data usage of such digital storage devices...
