Claim:
1. A method for controlling switching of a magnetoresistive random access memory (MRAM) device, comprising: delivering a current to the MRAM device, wherein the MRAM device is in a first state; measuring a voltage drop across the MRAM device in real-time with a resistance detector, wherein a voltage drop beyond a threshold voltage equates to switching from a first state to a second state, the first state different from the second state; determining whether the MRAM device has switched from the first state to the second state; and stopping the current delivered to the MRAM device; wherein responsive to determining that the MRAM device has switched from the first state to the second state comprises determining that the voltage drop across the magnetoresistive random access memory device exceeds a threshold value; wherein determining that the voltage drop across the MRAM device exceeds a threshold value comprises:
