Abstract
A resistive memory device configured to calibrate a reference resistor includes a calibration resistor circuit including a calibration resistor, a first reference resistor, a first sense amplifier configured to compare input currents, a first switch set including a plurality of switches, and a controller configured to control the first switch set to allow the first sense amplifier to compare a first reference current passing through the first reference resistor with a first read current passing through a first memory cell during a read operation and compare the first reference current with a first calibration current passing through the calibration resistor during a calibrate operation. A path of the first reference current during the read operation is different from a path of the first reference current during the calibrate operation.
