A memory anomaly processing method and system, an electronic device, and a storage medium. The method includes: reading a memory error quantity of a target memory bank from a memory error register; when the memory error quantity is greater than a preset value, executing a hot-removal operation on the target memory bank; calculating a memory delay parameter, and writing the memory delay parameter into a memory controller, wherein the memory delay parameter is waiting time after the memory controller controls the target memory bank to receive a read/write command; and executing a hot-addition operation on the target memory bank, whereby the memory controller continues to execute a read/write operation on the target memory bank based on the memory delay parameter. It can be seen that, according to the present application, the memory read/write error rate may be reduced.
