A semiconductor well of a non-volatile memory houses memory cells. The memory cells each have a floating gate and a control gate. Erasing of the memory cells includes biasing the semiconductor well with a first erase voltage having an absolute value greater than a breakdown voltage level of bipolar junctions of a control gate switching circuit of the memory. An absolute value of the first erase voltage is based on a comparison of a value of an indication of wear of the memory cells to a wear threshold value.

Method for writing in a non-volatile memory according to the ageing of the memory cells and corresponding integrated circuit

A managing method of the start-up phase of at least one micro fuel cell to be connected to a load includes: measuring a micro fuel cell voltage value across the micro fuel cell activated by means of a fuel injection; comparing the micro fuel cell voltage value with a first threshold voltage value; and establishing an operation mode of the micro fuel cell as follows: as long as the micro fuel cell voltage value is lower than the first threshold voltage value, the micro fuel cell operates in a first open circuit state, during which it is not connected to the load; when the micro fuel cell voltage value overcomes the first threshold voltage value, the micro fuel cell passes to a second pre-ignition state, during which it supplies a current value corresponding to the first threshold voltage value, according to a static voltage-current characteristic of the micro fuel cell.
