Patent ID: 8284595

Claim:
A magnetic random access memory comprising: first and second bit lines configured to be provided to extend in a first direction; a storage block configured to include at least one magnetroresistive element for storing data; and a reading circuit configured to determine said data, wherein said reading circuit includes: a feedback type voltage control circuit configured to include a first terminal electrically connected to said first bit line and a second terminal electrically connected to said second bit line, wherein said second terminal has a high impedance to prevent a steady-state current from flowing into at a time of a reading operation, wherein said feedback type voltage control circuit supplies a reading current from said first terminal to said first bit line at the time of said reading operation, wherein said storage block is configured such that said reading current flows from said first bit line to said magnetroresistive element and said magnetroresistive element is connected to said second bit line at the time of said reading operation, and wherein said feedback type voltage control circuit controls said reading current on the basis of a voltage supplied to said second terminal through the second bit line.
