1. A memory mapping method, comprising:
storing, in a memory, a feature map comprising a plurality of sets of data used for a neural network operation;
shifting a position of a portion of the data comprised in the feature map that is stored in the memory based on a parameter of the neural network operation; and
outputting data requested by the neural network operation from the feature map in which the position of the portion of the data is shifted based on a memory bandwidth.
