APPARATUSES AND METHODS FOR CYCLIC REDUNDANCY CALCULATION FOR SEMICONDUCTOR DEVICE

Abstract:

Apparatuses and methods of data error check for semiconductor devices are described. An example apparatus includes a plurality of data queue circuits and a CRC combine circuit. The plurality of data queue circuits includes a plurality of CRC calculator circuits. The plurality of CRC calculator circuits includes a CRC calculator circuit. The CRC calculator circuit receives a plurality of data bits and one or more check bits and further provides a plurality of CRC calculation bits. The CRC combine circuit receives the plurality of CRC calculation bits from the plurality of CRC calculator circuits, and further provides a result signal responsive to, at least in part, to the plurality of CRC calculation bits.
