Abstract: A method and a relevant apparatus for starting a boot program are provided. The method includes: when a boot request is detected, determining whether a first physical block in a NAND flash is a bad block; reading first boot data stored in the first physical block if the first physical block is not a bad block; determining whether the read first boot data has a data error; re-reading the first boot data from a first backup block when the read first boot data has a data error; determining whether the first boot data that is re-read from the first backup block has a data error; when the first boot data that is re-read from the first backup block has no data error, continuing to process other boot data that needs to be read to start the boot program, until start of the boot program is complete.

Abstract: Embodiments of the present invention disclose a method and an apparatus for controlling memory startup, and relate to the field of memory control technologies. The present invention is not limited to the number of pins of a control chip, thereby reducing costs. The method is applied to a control apparatus, where the control apparatus includes a preset data segment; the preset data segment includes at least one sub data segment; and each sub data segment is corresponding to one configuration type. The method includes: reading each sub data segment in a first data segment and performing a first operation on a sub data segment corresponding to a first configuration type to obtain a second data segment; performing matching between the second data segment and the preset data segment; and starting up the memory according to the first configuration type when the second data segment matches the preset data segment.

Abstract: This application provide a data processing method and apparatus, to store more user data in a limited quantity of storage chips in a design manner of reusing storage space corresponding to a second storage chip. In the method, a computer device first obtains user data, where the user data includes first data and second data. Then, the device writes the first data into a first storage chips, where a is an integer greater than 0. The device writes the second data and first check data into b second storage chips, where the first check data includes check data for the user data, and b is an integer greater than 0. In addition, the device writes second check data into c third storage chips, where the second check data includes check data for both the user data and the first check data, and c is an integer greater than 0.
