Abstract: A method for identifying non stuck-at faults in a read-only memory (ROM) includes generating a golden value of a victim cell, providing a fault-specific pattern through an aggressor cell, generating a test reading of the victim cell in response to the provided fault-specific pattern, and determining whether the ROM has at least one non stuck-at fault. The determination is based on a comparison of the golden value and the test reading of the victim cell.

Abstract: A system and a method for diagnosis flow for a read-only memory (ROM) includes determining whether a window of the ROM is faulty, based on a pre-computed signature and a computed signature corresponding to the window. Based on the determination, the size of the window is reduced to form at least two reduced windows. It is further ascertained whether the at least two reduced windows are faulty based on pre-computed signatures corresponding to the at least two reduced windows and computed signatures corresponding to the at least two reduced windows.
