Abstract: A method for writing into a one-time programmable memory of an integrated circuit includes attempting, by a memory control circuit of the integrated circuit, to write data in at least one first register of the one-time programmable memory; verifying, by the memory control circuit, whether the data has been correctly written in the at least one first register; and, in case the data has not been correctly written in the at least one first register, attempting, by the memory control circuit, to write the data in at least one second register of the one-time programmable memory.

Abstract: A level-shifter circuit receives one or more input signals in an input level domain and includes provides at an output node an output signal in an output level domain shifted with respect to the input level domain. The circuit includes output circuitry including a first drive node and a second drive node that receive first and second logical signals so that the output signal has a first output level or a second output level in the output level domain as a function of at least one of the first and second logical signals. The circuit includes first and second shift capacitors coupled to the first and second drive nodes as well as capacitor refresh circuitry.

Abstract: A power supply system includes a voltage application source, and a switched mode power supply having an output coupled to the voltage application source through a first path and through a second path different from the first path. A first node is coupled to the output of the switched mode power supply, the switched mode power supply being configured to couple the first node to the voltage application source through the first path in a first operating mode and through the second path in a different second operating mode. A digital regulator is coupled to the first node. A digital circuit is coupled to an output of the digital regulator. An analog regulator is coupled to the first node and an analog circuit coupled to an output of the analog regulator.

Abstract: According to one aspect, an integrated circuit includes: an electronic module configured to generate a voltage at an output, and an electronic control circuit coupled to an output of the electronic module, the electronic control circuit comprising an emissive electronic component. The electronic control circuit is configured to cause the emissive electronic component to emit light radiation as a function of a value of the voltage at the output of the electronic module relative to a value of an operating voltage of the electronic module, and the operating voltage is specific thereto during normal operation of this electronic module. The light radiation emitted by the emissive electronic component is configured to diffuse to an outer face of the integrated circuit.

Abstract: A testing device for electronic dies includes a first support part and a second support part configured to be removably assembled with each other. The first and second support parts together define at least one housing where at least one electronic die can be arranged to be tested. The electronic die has a first surface with contacting elements. The at least one housing includes a first portion. This at least one housing is arranged to enable the at least one electronic die to occupy a first position in the housing where the first surface is spaced apart from the first portion, and is further arrange to enable the at least one electronic die to occupy a second position in the housing where the first surface bears against the first portion.
