Dispositivo de memoria para aplicaciones de memoria resistiva

摘要

In a particular embodiment, a memory device is disclosed that includes a memory cell including a resistance-based memory element coupled to an access transistor. The access transistor has a first oxide thickness to enable operation of the memory cell at an operating voltage. The memory device also includes a first amplifier configured to couple the memory cell to a supply voltage that is greater than a voltage limit to generate a data signal based on a current through the memory cell. The first amplifier includes a clamp transistor that has a second oxide thickness that is greater than the first oxide thickness. The clamp transistor is configured to prevent the operating voltage at the memory cell from exceeding the voltage limit.
