Hybrid memory management of non-volatile memory (NVM) devices for use with recurrent neural networks

A method for use with a data storage device that includes a non-volatile memory (NVM) array, the method comprising:

• receiving data for storage in the NVM array;
• determining whether the data is neural network data or non-neural network data;
• in response to a determination the data is neural network data,
• storing at least three copies of the neural network data in the NVM array;
• reading the at least three copies of the neural network data from the NVM array;
• and
• performing a majority rules error correction procedure on the at least three copies of the neural network data read from the NVM array;
• and
• in response to a determination the data is non-neural network data,
• storing the non-neural network data in the NVM array;
• reading the non-neural network data from the NVM array;
• and
• performing an error correction code (ECC) procedure on the non-neural network data, the ECC procedure being different from the majority rules error correction procedure.

An apparatus for use with a data storage device that includes a non-volatile memory (NVM) array, the apparatus comprising:

• means for receiving data for storage in the NVM array;
• means for determining whether the data is neural network data or non-neural network data;
• means, operative in response to a determination the data is neural network data, for storing at least three copies of the neural network data in the NVM array;
• means for reading the at least three copies of the neural network data from the NVM array;
• means for performing a majority rules error correction procedure on the at least three copies of the neural network data read from the NVM array;
• means, operative in response to a determination the data is non-neural network data, for storing the non-neural network data in the NVM array;
• means for reading the non-neural network data from the NVM array;
• and
• means for performing an error correction code (ECC) procedure on the non-neural network data, the ECC procedure being different from the majority rules error correction procedure.

A non-transitory computer-readable medium comprising one or more instructions which when executed by a controller of a data storage device having a non-volatile memory (NVM) array causes the controller to:

• receive data for storage in the NVM array;
• determine whether the data is neural network data or non-neural network data;
• in response to a determination the data is neural network data, store at least three copies of the neural network data in the NVM array, read the at least three copies of the neural network data from the NVM array, and perform a majority rules error correction procedure on the at least three copies of the neural network data read from the NVM array;
• and
• in response to a determination the data is non-neural network data, store the non-neural network data in the NVM array, read the non-neural network data from the NVM array, and perform an error correction code (ECC) procedure on the non-neural network data, the ECC procedure being different from the majority rules error correction procedure.
