    Abstract: Apparatus and methods for carrying out operations in a non-volatile memory cell having multiple memory states are disclosed. One of the methods is a method for programming N bits in a non-volatile memory cell configured to store up to N+1 bits, where N is an integer greater than zero. The method for programming includes programming N bits of data in the cell. The method for programming also includes programming an additional bit of data that is a logical function of the N bits of data in the cell. The cell is configured to provide 2N+1 threshold voltage ranges for bit storage and, in accordance with the logical function: i) a first set of 2N threshold voltage ranges of the 2N+1 threshold voltage ranges are used to store the N bits of data; and ii) a remaining second set of 2N threshold voltage ranges alternating with the first set are unused.

    Abstract: A semiconductor device includes a bridging device having an external data interface, an external status interface, and a plurality of internal data interfaces. A plurality of memory devices are each connected to the bridging device via one of the internal data interfaces. Each of the memory devices has a ready/busy output connected to an input of the bridging device. The bridging device is configured to output a current state of each ready/busy output in a packetized format on the external status interface in response to a status request command received on the external status interface; and read information from a status register of a selected memory device over one of the internal data interfaces and provide the information on the external data interface in response to a status read command received on the external data interface. A method of operating a semiconductor device is also disclosed.
