  • Publication number: 20240137037
    Abstract: The present disclosure provides a comparator including a non-volatile memory device. The comparator is configured to compare an analog input voltage and a reference voltage and produce a digital output indicative of the comparison result. The digital output may represent a resistance state of the non-volatile memory device in response to the application of the reference voltage and the analog input voltage to the comparator. The present disclosure further provides analog-to-digital converters (ADCs) utilizing the comparator. The non-volatile memory device includes, for example, a memristor device, an MRAM (Magnetoresistive random access memory) device, a phase-change memory (PCM) device, a floating gate, a spintronic device, etc.

  • Publication number: 20240137038
    Abstract: The present disclosure provides a voltage divider circuit utilizing non-volatile memory devices. The non-volatile memory device may include, for example, a memristor device, an MRAM (Magnetoresistive random access memory) device, a phase-change memory (PCM) device, a floating gate, a spintronic device, etc. The voltage divider circuit may include one or more first non-volatile memory devices that form a resistor ladder. The resistor ladder may produce a plurality of reference voltages when the resistor ladder is connected between two voltages.
