Abstract
Memory test hardware is provided for generating signals for testing a first memory array and a second memory array. The first memory array and the second memory array may be any two of main memory array, a spare memory array, and reconfiguration memory array, or the apparatus may be adapted for testing all three memory arrays. The memory test hardware may include a controller for generating control signals, a data generator coupled to the controller for generating data signals, and an address generator coupled to the controller for generating address signals. The test device may further include an output data evaluator and repair unit for receiving signals from the main memory array and the spare memory array and for detecting faults in those arrays.
