Patent ID: 7272036

Claim:
A thin film magnetic memory device comprising: a plurality of first write current lines for selectively feeding a first data write current; a plurality of magnetic memory cells into which data is written by application of magnetic field produced by said first data write current; a first switching element provided corresponding to one end of each of said first write current lines; wherein said first switching element is arranged to allow said first data write current to flow by connecting corresponding one of said first current write lines charged to a first voltage to a second voltage different from said first voltage; a second switching element provided corresponding to the other end of each of said first write current lines, wherein said second switching element is conducted during at least a part of a non-conducted period of said first switching element, so as to electrically connect said corresponding first write current line to said first voltage, and is rendered non-conducting during a conducted period of said first switching element, so as to electrically disconnect said corresponding first write current line from said first voltage.
