Abstract
An integrated circuit containing memory includes IEEE 1149.1 (JTAG) controlled self-repair system that permits permanent repair of the memory after the integrated circuit has been packaged. The JTAG controlled self-repair system allows a user to direct circuitry to blow fuses using an externally supplied voltage to electrically couple or isolate components to permanently repair a memory location with JTAG standard TMS and TCK signals. The system may optionally sequentially repair more than one memory location using a repair sequencer.
