    摘要: A method for self-contained testing within a DRAM comprises the DRAM receiving an instruction from an external processor to test a memory core on the DRAM, and the DRAM self-testing the memory core with one or more BIST pattern stored in a multipurpose register on the DRAM. Optionally, the step of self-testing may include writing the BIST pattern into all locations of the memory core, reading each location of the memory core, and comparing the content read from each location of the memory core with the BIST pattern, wherein a negative comparison indicates a failure has occurred. In a further option, the method may further comprise, after testing the DRAM, initializing the DRAM with an INIT pattern stored in the multipurpose register on the DRAM.

    摘要: Fault injection in dynamic random access memory (‘DRAM’) modules for performing built-in self-tests (‘BISTs’) including establishing, in the mode registers of the DRAM modules by the memory controller through the shared address bus, an injection of a fault into one or more signal lines of a DRAM module, the fault characterized by a fault type; writing data by the memory controller through a data bus to the DRAM modules, the data identifying a particular DRAM module; and responsive to receiving the data, injecting, by the particular DRAM module, the fault characterized by the fault type into the one or more signal lines of the particular DRAM module.
