STORAGE DEVICE USING NEURAL NETWORK AND OPERATING METHOD FOR AUTOMATIC REDISTRIBUTION OF INFORMATION AND VARIABLE STORAGE CAPACITY BASED ON ACCURACY-STORAGE CAPACITY TRADEOFF THEREOF

Abstract

Provided are a storage device using a neural network and an operating method of the storage device for automatic redistribution of information and variable storage capacity based on accuracy-storage capacity tradeoff that may learn input information using the neural network and may store the learned information. The neural network may include a plurality of input neurons and a plurality of output neurons; at least one stable synapse configured to connect at least one of the input neurons and at least one of the output neurons, respectively; and at least one flexible synapse configured to connect at least one remaining of the input neurons and at least one remaining of the output neurons, respectively.
