Abstract
An integrated circuit is provided for self-repair of a memory array. The circuit includes first word lines coupled to first memory rows of the memory array, one first word line for each bit of a line address word, second word lines coupled to one or more spare memory rows of the memory array. Repair configuration data is stored in memory cells within the integrated circuit to direct memory accesses to spare memory rows rather than dysfunctional first memory rows. A memory cell may be based on a correlated electron switch (CES). A built-in self-test circuit is provided to facilitate setting of repair configuration data. The repair data may be reconfigurable, enabling operating margins to be improved by testing under various operating conditions.
