A method of controlling a non-volatile memory device includes comparing the number of banks that are in operating states with a threshold value. If the number of the banks is smaller than the threshold value, data stored in a standby bank is read. If there is no bank having data to be read, a standby bank is programmed. If the number of the banks is equal to or greater than the threshold value or if the reading or the programming is performed, it is determined whether there is a reading or programming command to be performed. If there is the reading or programming command to be performed, the process is repeated from the comparing step. The programming may include programming of a most significant bit (MSB) page or a least significant bit (LSB) page.

The apparatus includes a data normalization unit, a neural network problem prediction unit, and a transition change prediction unit. The data normalization unit creates normalization transformation values by performing normalization transformation based on threshold value ranges for a plurality of pieces of vehicle network data. The neural network problem prediction unit creates a neural network problem prediction value by predicting a mixed problem with the vehicle using a multi-artificial neural network model, created based on a learning data set related to mixed problems having previously occurred in the vehicle and the normalization transformation values. The transition change prediction unit predicts a change in transition for the mixed problem according to a change in the neural network problem prediction value, by analyzing the neural network problem prediction value and previous neural network problem prediction values previously created in the vehicle.
