  • On chip diagnosis block with mixed redundancy
    Patent number: 7386769
    Abstract: On chip diagnosis method and on chip diagnosis block with mixed redundancy (IO redundancy and word-register redundancy) is provided. During a BIST (Built-In Self Test), information needed to apply redundancy resources is stored inside two arrays (fill_array, shift_array) on chip. A final diagnosis may apply redundancy resources based on this stored information. The first array (fill_array) is used to keep a minimum error mapping and the second array (shift_array) is used to control the fill of the first array.
    Type: Grant

  • Fuse blowing interface for a memory chip
    Patent number: 7085182
    Abstract: A fuse blowing interface (7) for a memory chip (1) comprising a latch register for latching a calculated memory repair solution when a prefuse request signal is received from an external tester device (8); and a fuse blowing unit with electrical fuses which are blown according to the calculated memory repair solution when a blow request signal is received from the external tester device (8).
