1. An electronic device including a semiconductor memory, the semiconductor memory comprising:
a cell array including different cell regions each of which includes a plurality of memory cells, each memory cell including a transistor and a resistance variable element; a write driver circuit coupled to the cell array to supply a write current for storing data in a memory cell selected among the plurality of memory cells; and a back bias voltage supply unit coupled to the different cell regions of the cell array and configured to supply back bias voltages with different levels to the respective cell regions, wherein the levels of the back bias voltages to be supplied to the respective regions are determined based on distances between the write driver circuit and the respective cell regions.
