Abstract: Systems and methods relate to providing a constant sensing current for reading a resistive memory element. A load voltage generator provides a load voltage based on a current mirror configured to supply a constant current that is invariant with process-voltage-temperature variations. A data voltage is generated based on the generated load voltage, by passing a sensing current mirrored from the constant current, through the resistive memory element. A reference voltage is generated, also based on the generated load voltage and by passing reference current mirrored from the constant current, through reference cells. A logical value stored in the resistive memory element is determined based on a comparison of the data voltage and the reference voltage, where the determination is free from effects of process-voltage-temperature variations.

Abstract: Systems and methods relate to providing a correct reference voltage for reading a resistive memory element such as a magnetoresistive random access memory (MRAM) bit cell. Two or more reference voltages are provided for each MRAM bit cell and a correct reference voltage is selected from the two or more reference voltages for reading the MRAM bit cell. The correct reference voltage meets sensing margin requirements for reading the MRAM bit cell and overcomes non-idealities and offset voltages in read circuitry for reading the MRAM bit cell. An indication of the correct reference voltage is stored in a non-volatile latch or other non-volatile programmable memory and provided to the read circuitry.

Abstract: Systems and methods for reducing a probability of read disturbance during a read operation on a resistive memory bit cell include a dual stage sensing scheme, which is used to reduce pulse widths of sensing currents for reading the resistive memory bit cell. During a first stage of the read operation on the resistive memory bit cell, a first sensing current is passed in a first direction through the resistive memory bit cell, and during a second stage of the read operation, a second sensing current is passed in an opposite, second direction through the resistive memory bit cell. Durations of the first and second stages are each equal to half of the duration of the read operation, which reduces pulse width of the first and second sensing currents. Probability of read disturbance occurring is limited to at most one of the first or second stages.

Abstract: A low sensing current non volatile flip flop includes a first stage to sense a resistance difference between two magnetic tunnel junctions (MTJs) and a second stage having circuitry to amplify the output of the first stage. The output of the first stage is initially pre-charged and determined by the resistance difference of the two MTJs when the sensing operation starts. The first stage does not have a pull-up path to a source voltage (VDD), and therefore does not have a DC path from VDD to ground during the sensing operation. A slow sense enable (SE) signal slope reduces peak sensing current in the first stage. A secondary current path reduces the sensing current duration of the first stage.

Abstract: An offset canceling dual stage sensing method includes sensing a data value of a resistive memory data cell using a first load PMOS gate voltage generated by a reference value of a resistive memory reference cell in a first stage operation. The method also includes sensing the reference value of the resistive memory reference cell using a second load PMOS gate voltage generated by the data value of the resistive memory data cell in a second stage operation of the resistive memory sensing circuit. By adjusting the operating point of the reference cell sensing, an offset canceling dual stage sensing circuit increases the sense margin significantly compared to that of a conventional sensing circuit.
