    Abstract: An embodiment power-on-reset circuit, having a power supply input to receive a power supply voltage, generates a reset signal with a value switching upon the power supply voltage crossing a POR detection level. The power-on-reset circuit has: a PTAT stage having a left branch and a right branch and generating a current equilibrium condition between the currents circulating in the left and right branches upon the power supply voltage reaching the POR detection level; and an output stage coupled to the PTAT stage and generating the reset signal, with the value switching at the occurrence of the current equilibrium condition for the PTAT stage. The power-on-reset circuit further comprises a detection-level generation stage, coupled to the PTAT stage as a central branch thereof to define the value of the POR detection level.

    Abstract: A voltage regulator receives an input voltage and produces a regulated output voltage. A first feedback network compares a feedback signal to a reference signal to assert/de-assert a first pulsed control signal when the reference signal is higher/lower than the feedback signal. A second feedback network compares the output voltage to a threshold signal to assert/de-assert a second control signal when the threshold signal is higher/lower than the output voltage. A charge pump is enabled if the second control signal is de-asserted and is clocked by the first pulsed control signal to produce a supply voltage higher than the input voltage. A first pass element is enabled when the second control signal is asserted and is selectively activated when the first pulsed control signal is asserted. A second pass element is selectively activated when the second control signal is de-asserted.

    Abstract: In an embodiment, a non-volatile memory device includes a memory array divided into a plurality of tiles, and a row decoder that includes main row decoding units associated to a respective group of tiles. The row decoded further includes local row decoding units, each associated to a respective tile for carrying out selection and biasing of corresponding word lines based on decoded address signals and biasing signals. Each local row decoding unit has logic-combination modules coupled to a set of word lines and include, for each word line, a pull-down stage for selecting a word line, and a pull-up stage. The pull-up stage is dynamically biased, alternatively, in a strong-biasing condition towards a tile-supply voltage when the word line is not selected, or in a weak-biasing condition when the word line is selected.
