Semiconductor devices including variable resistance elements and methods of operating semiconductor devices
Abstract:
In a method of operating a semiconductor device, a resistance value of a variable resistance element is changed from a first resistance value to a second resistance value by applying a first voltage to the variable resistance element; and a first current that flows through the variable resistance element is sensed. A second voltage for changing the resistance value of the variable resistance element from the second resistance value to the first resistance value is modulated based on a dispersion of the first current, and the first voltage is re-applied to the variable resistance element based on a dispersion of the first current.
Abstract(Chinese):

在操作半导体器件的方法中，通过向可变电阻元件施加第一电压，可变电阻元件的电阻值从第一电阻值改变为第二电阻值; 并且感测流过可变电阻元件的第一电流。 基于第一电流的偏差来调制用于将可变电阻元件的电阻值从第二电阻值改变为第一电阻值的第二电压，并且基于第一电压将第一电压重新施加到可变电阻元件 第一电流的分散。
