摘要： 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.

摘要： 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.

摘要： Various embodiments address various difficulties with source side sensing difficulties in various memory architectures, such as 3D vertical gate flash and multilevel cell memory. One such difficulty is that with source side sensing, the signal amplitude is significantly smaller than drain side sensing. Another such difficulty is the noise and reduced sensing margins associated with multilevel cell memory. In some embodiments the bit line is selectively discharged prior to applying the read bias arrangement.
