Abstract
A memory device and a method for operating the memory device are provided. A resistive memory cell connected to a first node and configured to include a variable resistive element and an access element for controlling a current flowing through the variable resistive element. A detection circuit detects a threshold voltage of the access element and provides a detection current to a sensing node. A clamping circuit connected between the first node and the sensing node receives a first read voltage and ramps up a voltage of the first node. The first node is discharged by a discharge circuit when the detection current becomes equal to a bit line current flowing through the first node while the clamping circuit ramps up the voltage of the first node. A sense amplifier transitions an output voltage value when a voltage level of the sensing node becomes lower than a reference voltage.
