Abstract
A device is connected in parallel with an MTJ structure of an MRAM bit to shunt photocurrent away from and/or limit voltage across the MTJ structure during a dose rate event. The device may include at least one transistor and/or at least one diode. One device may be used to protect an entire row and/or column of MRAM bits. As a result, the MRAM bits are protected during a dose rate event.
