摘要： Embodiments relate to the field of storage technologies. The method is applied to a flash device whose first physical storage space stores a data block at a first security level and a data block at a second security level and whose second physical storage space stores a data block at a second security level. The method includes: receiving a data write request used to request to write target data, and obtaining a security level of the target data; and writing the target data into the first physical storage space if the security level of the target data is the first security level; or writing the target data into the second physical storage space or writing the target data into the second physical storage space and the first physical storage space if the security level of the target data is the second security level.

摘要： Embodiments of this application disclose a packaging module and an electronic device. Both a first surface and a second surface of a PCB in the packaging module are covered with a molding layer, a conductive pin is electrically connected to the PCB, the conductive pin is packaged inside the molding layer along a stacking direction of the PCB and the molding layer, and the conductive pin is partially exposed on an outer surface of the molding layer. When the packaging module performs electrical interaction with another element, the PCB outputs or inputs an electrical signal by using the conductive pin. In this way, there is no need to reserve a through hole on a packaging side of the packaging module, the packaging module may be arranged at a position close to a chip, and there are short wires between the packaging module and the chip.

摘要： A data query method and apparatus are disclosed. The method includes: determining a target directory block including m directory entries and m file names, where the m directory entries one-to-one correspond to the m file names, and the m directory entries and the m file names are sequentially arranged according to a preset rule; determining a current first set and a current second set based on a binary search algorithm and the target directory block; determining a first common prefix between a to-be-accessed file name and a file name in the current second set; comparing the to-be-accessed file name with a third file name character by character from a first character after the first common prefix; and if the to-be-accessed file name is the same as the third file name, obtaining data of a to-be-accessed file based on a directory entry corresponding to the third file name.
