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.
