Abstract: A memory controller includes a voltage control module that operates to isolate a target memristor of a memory crossbar array. The voltage control module applies a column voltage to a column line coupled to the target memristor, applies a first row voltage to all row lines not coupled to the target memristor and a second row voltage to a row line coupled to the target memristor, and senses a current through the target memristor to determine a state of the target memristor. The memory crossbar array includes a plurality of column lines, a plurality of row lines, a plurality of memristors, and a plurality of shorting switches. Each memristor is coupled between a unique combination of one column line and one row line. Each shorting switch has a high impedance resistor and a low impedance transistor, and each shorting switch is coupled to an end of a unique row line.

Abstract: A device for regulating memristor switching pulses is described. The device includes a voltage source to supply a voltage to a memristor. The device also includes a voltage detector to detect a memristor voltage. The memristor voltage is based on an initial resistance state of the memristor and the voltage supplied by the voltage source. The device also includes a comparator to compare the memristor voltage with a target voltage value for the memristor. The device also includes a feedback loop to indicate to a control switch when the memristor voltage is at least equal to the target voltage value. The device also includes a control switch to cut off the memristor from the voltage source when the memristor voltage is at least equal to the target voltage value.
