One example includes a system. The system includes an error injection system. The error injection system includes an error injector to store a programmable control structure to define a memory error. The error injector being further used to inject the memory error into a respective one of a plurality of memory storage elements associated with a memory system at a predetermined address via an address controller and to determine if the memory error at the predetermined address associated with the respective one of the plurality of memory storage elements is corrected via error-correcting code (ECC) memory associated with the memory system.
