An electronic device includes a coding module that determines whether a parameter of an artificial neural network is an outlier, depending on a value of the parameter and compresses the parameter by truncating a first bit of the parameter when the parameter is a non-outlier and truncating a second bit of the parameter when the parameter is the outlier, and a decoding module that decodes a compressed parameter.

Electronic device performing outlier-aware approximation coding and method thereof

A memory controller includes an error correction circuit that converts some bits of first data into parity bits for an error correction operation and generates second data including remaining bits of the first data and the parity bits replaced from the some bits, and a physical layer that transmits the second data instead of the first data to a memory device.
