A memory self-test system is provided comprising a self-test controller operable in self-test mode to generate a sequence of generated memory addresses for performing memory access operations associated with the memory test algorithm having an associated memory cell physical access pattern. A programmable re-mapper is operable to re-map the sequence of generated memory addresses derived from the self-test instruction to a sequence of re-mapped memory addresses. The programmable re-mapper performs this re-mapping in response to programmable mapping selection data. The re-mapping of the generated memory addresses to re-mapped memory addresses ensures that the memory cell accesses performed during execution of the memory self-test are consistent with the associated memory cell physical access pattern regardless of the particular implementation of the memory array.
