    Abstract: Channel selection information indicate positions of data bits of input data, positions of error correction code (ECC) parity bits for correcting errors in the input data, and positions of state shaping parity bits. The ECC parity bits and the state shaping parity bits are generated to cause a decrease in a quantity of memory cells, of the plurality of memory cells, in which at least one target state among a plurality of states is programmed. An alignment vector is generated based on aligning the data bits of the input data, the ECC parity bits, and the state shaping parity bits, based on the channel selection information. A codeword is generated based on simultaneously performing state shaping and ECC encoding with respect to the alignment vector. Write data are written in the nonvolatile memory device based on the codeword.

    Abstract: A storage system includes a host device and a storage device. The host device provides first input data for data storage function and second input data for artificial intelligence (AI) function. The storage device stores the first input data from the host device, and performs AI calculation based on the second input data to generate calculation result data. The storage device includes a first processor, a first nonvolatile memory, a second processor and a second nonvolatile memory. The first processor controls an operation of the storage device. The first nonvolatile memory stores the first input data. The second processor performs the AI calculation, and is distinguished from the first processor. The second nonvolatile memory stores weight data associated with the AI calculation, and is distinguished from the first nonvolatile memory.
