The application relates to an error injection method and device, computer equipment and a readable storage medium. The method comprises the following steps: determining an error injection requirement based on a configuration operation, the configuration operation being used for configuring at least one or a combination of a target logical address, an error type and a trigger condition; converting the error injection requirement into an error injection command, storing the error injection command into a content addressable memory (CAM) for scheduling, and obtaining a scheduling result; and according to the scheduling result, issuing the error injection command and a dynamic random access memory (DRAM) physical address to a corresponding DRAM control unit to execute the error injection through the DRAM control unit. Thus, the system can remain in a normal operation state during the entire error injection process, without entering a special test mode, ensuring the normal execution of a refresh operation, and the interaction between AXI internal and address mapping modules is reused, without affecting business continuity, so that the universality is enhanced.
