Abstract

A nonvolatile memory device includes a differential current driver that receives a first differential signal and a second differential signal, which are based on a temperature, and generates a first compensation current and a second compensation current corresponding to a difference value between the first and second differential signals. A current mirror circuit copies a first current, which is a sum of a reference current and the first compensation current, to generate a second current having a same value as a value of the first current and regulates the reference current depending on a difference value of the second current and the second compensation current. A trimming circuit generates a program current or a read current based on the regulated reference current.
