    摘要: Read and write operations of a non-volatile memory (NVM) bitcell have different optimum parameters resulting in a conflict during design of the NVM bitcell. A single bitline in the NVM bitcell prevents optimum read performance. Read performance may be improved by splitting the read path and the write path in a NVM bitcell between two bitlines. A read bitline of the NVM bitcell has a low capacitance for improved read operation speed and decreased power consumption. A write bitline of the NVM bitcell has a low resistance to handle large currents present during write operations. A memory element of the NVM bitcell may be a fuse, anti-fuse, eFUSE, or magnetic tunnel junction. Read performance may be further enhanced with differential sensing read operations.

    摘要: An offset compensated memory element voltage supply including a differential amplifier with a compensation circuit, and a transistor with a gate connected to the output of the differential amplifier. The compensation circuit of the differential amplifier includes a compensation capacitor that stores a compensation voltage during a calibration phase, and applies the stored compensation voltage to a compensation input of the compensation circuit of the amplifier during a measurement phase. Feedback from a source of the transistor controls the output of the differential amplifier to maintain a standard voltage across a resistive memory element connected to the source during measurement of the resistance of the resistive memory element, and the compensation circuit improves the accuracy of the voltage across the resistive memory element by compensating for an offset voltage of the differential amplifier.
