  • Patent number: 10481965
    Abstract: Counting status circuits are electrically coupled to corresponding status elements. The status elements selectably store a bit status of a bit line coupled to a memory array. The bit status can indicate one of at least pass and fail. The counting status circuits are electrically coupled to each other in a sequential order. Control logic causes processing of the counting status circuits in the sequential order to determine a total of the memory elements that store the bit status. The total number of memory elements that store the bit status indicate the number of error bits or non-error bits, which can help determine whether there are too many errors to be fixed by error correction codes.

  • Publication number: 20160077153
    Abstract: An integrated circuit memory includes a memory array, including a plurality of data lines. A buffer structure is coupled to the plurality of data lines, including a plurality of storage elements to store bit-level status values for the plurality of data lines. The memory includes logic to indicate bundle-level status values of corresponding bundles of storage elements in the buffer structure based on the bit-level status values of bits in the corresponding bundles. A plurality of bundle status circuits is arranged in a daisy chain and coupled to respective bundles in the buffer structure, producing an output of the daisy chain indicating detection of a bundle in the first status. Control circuitry executes cycles to determine the output of the daisy chain, each cycle clearing a bundle status circuit indicating the first status if the output indicates detection of a bundle in the first status in the cycle.

  • Publication number: 20150380112
    Abstract: An integrated circuit includes an array of memory cells that is arranged into rows, main columns, and redundant columns that perform repairs in the array. The main columns and the redundant columns are divided into row blocks. Bit lines couple the main columns to status memory indicating repair statuses of the repairs by the redundant columns. The integrated circuit receives a command, and performs an update on the status memory with the repair statuses specific to particular ones of the row blocks in a portion of the memory accessed by the command. Alternatively or in combination, the status memory has insufficient size to store the repair statuses of multiple ones of the row blocks of the main columns.
