  • Patent number: 7457187
    Abstract: A design structure for repairing an integrated circuit during operation of the integrated circuit. The integrated circuit comprising of a multitude of memory arrays and a fuse box holding control data for controlling redundancy logic of the arrays. The design structure provides the integrated circuit with a control data selector for passing the control data from the fuse box to the memory arrays; providing a source of alternate control data, external of the integrated circuit; and connecting the source of alternate control data to the control data selector. The design structure further passes the alternate control data from the source thereof, through the control data selector and to the memory arrays to control the redundancy logic of the memory arrays.

  • Patent number: 6711040
    Abstract: A method and structure for improving a content addressable memory array has a plurality of serially connected memory sub-arrays (which include at least one memory cell), a matchline connected to each of the sub-arrays, a valid memory cell, a comparator receiving input from the matchline and valid memory cell, a sinkline output from the comparator, and a precharge device. The sinkline and matchline are reset from a first voltage to a second voltage depending upon the results of a compare operation of the input data to the data in the storage device. When the second voltage appears on the matchline and the first voltage appears on the sinkline this indicates a match between the data within all of the sub-arrays and the input data.
