Electronic device

An electronic device including a semiconductor memory, wherein the semiconductor memory comprises:

• a plurality of resistive storage cells each structured to exhibit different resistance values for storing data;
• a reference resistance cell;
• a comparison block electrically coupled to the plurality of resistive storage cells through a first input terminal and the reference resistance cell through a second input terminal, the comparison block operable to compare a cell current flowing through the first input terminal and a reference current flowing through the second input terminal;
• a first clamp part having terminals including a first terminal coupled to the plurality of resistive storage cells, a second terminal coupled to the first input terminal, and a third terminal coupled to a first node, and operable to control a maximum current amount of the cell current depending on a voltage level of the first node;
• a second clamp part coupled between the reference resistance cell and the second input terminal, and operable to control a maximum current amount of the reference current depending on the voltage level of the first node;
• a voltage stabilization block electrically coupled to the first clamp part through the first node and operable to stabilize a voltage of the first node during a charging or a discharging period;
• and
• a switching part electrically coupled with the first node and the voltage stabilization block in the charging period or the discharging period.
