Memory bank error repairing method and device

The invention relates to the technical field of computers, and discloses a memory bank error repairing method and device, and the method comprises the steps: S1, reading a memory bank identification mark built in an SPD particle; S2, detecting the memory bank which is successfully identified, and determining a memory error of the memory bank; and S3, shielding a memory area corresponding to the memory error. The method comprises the following steps of: determining a memory error of a memory bank by reading memory bank identification marks built in SPD particles and detecting the memory bank which is successfully identified; shielding the memory area corresponding to the memory error according to the determined memory bank error, wherein for the shielded memory area, the system does not useany more, and the unshielded memory area can normally operate, so that on one hand, the requirement on the use level of memory particles is reduced; on the other hand, repeated errors of the memory area are avoided, and the
