Abstract

The embodiment of the invention discloses a memory fault processing method and device, equipment and a storage medium, and belongs to the technical field of computers. In the embodiment of the invention, the fault analysis result is obtained by analyzing the historical fault information, and then the fault of the memory is repaired according to the fault analysis result, so that the memory fault can be analyzed more accurately. In addition, according to the scheme, memory fault repair can be started without cold reset, that is, memory faults can be repaired in time, system downtime is prevented, and service influences are reduced.

Description

[0001] This application claims the priority of the Chinese patent application with the application number 202010569797.2 and the title of the invention "A Method for Handling Memory Faults" filed on June 20, 2020, the entire contents of which are incorporated by reference in this application. technical field [0002] The embodiments of the present application relate to the technical field of computers, and in particular, to a memory fault processing method, device, device, and storage medium. Background technique [0003] Memory is one of the important components of a device. Typically, memory consists of multiple banks (also known as memory matrices), and each bank contains multiple rows of memory. During the use of memory, failures often occur due to various reasons, and the proportion of memory failures caused by memory row failures is very high. Therefore, the repair of memory row failures can be used as an important repair method for memory failures. [0004] In a rela...
