In our work, we investigate the recording and readout performance of such phase-change memories and demonstrate experimental and simulation results which are based on a particular medium stack (Si/TiN/DLC/GST/DLC). The recording is achieved by injecting electrical current from a conductive tip to the storage medium to cause phase transformation through Joule heating, while readout is realised by sensing the current variation due to the significant differences in the electrical resistivity between the amorphous and crystalline phases. The experimental results clearly show that a crystalline bit with approximately 30nm diameter can be produced and readback, in good agreement with the corresponding simulations of the write/read processes.
