Abstract: A method, and a corresponding device, provides for testing computer memory having a number of memory elements. The method includes the steps of initializing each memory element to zero, using a seeded random number generator, determining a random address that corresponds to a start point in the memory range, using the seeded random number generator, writing a random data value to the random address, repeating the two previous steps until all memory elements have been written to with random data values, conducting a refresh test of the memory range, and using the same seeded random number generator and the same written random data values, reading each of the memory elements in the memory range.
