Method and apparatus for in-system management and repair of semi-conductor memory failure
A memory having a redundancy area is operated in a normal mode and an error is detected. A selecting selects between in-line repair process and off-line repair. In-line repair applies a short term error correction, which remaps a fail address to a remapped memory area of the memory. An in-system repair is applied, for a one-time programmed remapping of the fail address to a redundancy area of the memory. In-system repair utilizes idle time of the memory to maintain valid memory content.
