    摘要： A sense amplifier for reading a memory cell is provided. The sense amplifier includes a first input branch for applying a biasing voltage to the memory cell through regulation means and for receiving a first input current indicative of a state of the memory cell, the regulation means including a first controlled element having a voltage-controlled conductivity and a control element for applying a first control voltage corresponding to the first input current to the first controlled element, and sensing means for determining the state of the memory cell according to a comparison between the first input current and a reference value; the sensing means includes a second input branch including a second controlled element (M3m), shifting means (215m) for applying a second control voltage equal to the first control voltage shifted by a predetermined offset to the second controlled element, a second input current corresponding to the second control voltage flowing through the second input branch, and comparison means for comparing the second input current with the reference value.

    摘要： An electronic device including a microprocessor, a circuit generating a clock signal, and memories of both the volatile type and the non-volatile type, incorporates a circuit for generation of a reset signal capable of detecting a stop in the oscillation of said clock signal and generating a logic signal coupled with the reset input of the microprocessor. The circuit monitors the clock signal applied to the device and, if an irregularity is detected, generate a reset signal holding the microprocessor in a safe state. The reset signal is held until the circuit generating the clock signal resumes normal operation.
