ELECTRONIC DEVICES HAVING SEMICONDUCTOR MAGNETIC MEMORY UNITS

摘要

An electronic device comprising a semiconductor memory unit that includes a resistance variable element configured to be changed in a resistance value according to a value of data stored therein; a first reference resistance element having a first resistance value; a second reference resistance element having a second resistance value larger than the first resistance value; and a comparison unit configured to receive a voltage corresponding to the resistance value of the resistance variable element through a first input terminal and a second input terminal thereof, a voltage corresponding to the first resistance value of the first reference resistance element through a third input terminal, and a voltage corresponding to the second resistance value of the second reference resistance element through a fourth input terminal, the comparison unit configured to output a result of comparing inputs to the first input terminal and the second input terminal and inputs to the third input terminal and fourth input terminal.
