A method is disclosed for identifying ROM memories. The method first determines whether the same data is read from a predetermined unit of memory during successive reads and, if so, determines whether the read data includes more than a predetermined minimum number of different data bytes. If both tests are true, then the predetermined unit of memory is considered to be occupied by read only memory. If either test fails, then the predetermined unit of memory is considered to be unoccupied.
