An apparatus and a method for reading a phase-change memory cell are described. A circuit includes a current ramp circuit. A current forcing module is coupled with the current ramp circuit. A Veb emulation circuit is coupled with the current forcing module by a voltage adder, the voltage adder to sum an output from the Veb emulation circuit and a high impedance voltage source. A method includes forcing a current ramp into both a bitline and a dummy bitline, the dummy bitline having a voltage. The method also includes tripping a comparator when the current ramp provides a storage voltage with a predefined value, the storage voltage associated with the phase-change memory cell, and the predefined value independent from a resistance value of the phase-change memory cell and added in series to the voltage of the dummy bitline.
