ABSTRACT:
Circuits for writing, reading, and erasing a programmable metallization cell are disclosed. The programming circuits compensate for parasitic capacitance and/or parasitic resistance. The parasitic resistance and/or capacitance is compensated for using a feedback loop or a time current filter. Various circuits also measure a switching speed of the programmable metallization cell.
