Abstract: Embodiments of this application provide a data storage method, a data reading method, and a related device. The method includes: obtaining output data from a processor, where the output data includes target data to be written into a memory and poison data indication information corresponding to the target data, and the poison data indication information indicates whether the target data is poison data; and writing preset data into the memory based on the poison data indication information, or writing to-be-written data determined based on the target data into the memory. In the foregoing technical solution, the poison data can be indicated without sacrificing a parity bit. Therefore, according to the foregoing technical solution, the poison data stored in the memory can be identified, and a problem that an error correction capability is degraded due to sacrifice of the parity bit is avoided.

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.
