  • Publication number: 20240086891
    Abstract: A first near-field communication device detects the presence of a second near-field communication device located within range. In response to that detection, there is an initiation of a near-field communication between the first and second devices. In case of a failure of the initiation of the near-field communication, instead an initiation of a contactless bank transaction between the first and second devices occurs.

  • Publication number: 20240087652
    Abstract: A nonvolatile memory device has a “split-voltage” architecture and includes columns of memory words formed on each row by groups of memory cells. All state transistors for memory cells of a memory word are gate controlled by a control element. All control elements of a same row are controlled by a first control signal generated by a first row control circuit in response to a set-reset (SR) latch output signal output for a selected row. In order to write a piece of data in a memory word, the first row control circuit confers onto the first control signal an erasing voltage corresponding to a first logic state of the first control signal and then a programming voltage corresponding to a second logic state of the first control signal without modifying, between erasing and programming the memory word, the state of the latch output signal for the selected row.

  • Patent number: 11929748
    Abstract: A wobulated signal generator includes a chain of delay elements and control circuitry. The chain of delay elements includes first delay elements, second delay elements, and third delay elements. The control circuitry, in operation, enables a number of the first delay elements, disables a number of the third delay elements, and enables a selected number of the second delay elements, defining a period of time between two consecutive rising edges of a digital wobulated signal at an output of the wobulated signal generator. The control circuitry monitors an average frequency of the digitally wobulated signal, and selectively modifies the number of enabled first delay elements and the number of disabled third delay elements based on the monitored average frequency of the digitally wobulated signal.

  • Publication number: 20240069901
    Abstract: A server builds an update file to update software. The server compiles source code of an updated version of the software, generating a binary file of the updated version of the software. Memory locations are mapped to sections of the binary file based on mappings of sections of a binary file of a prior version of the software. Bits of sections of a plurality of sections of the binary file of the prior version are logically combined, bit-by-bit, with bits of corresponding sections of the binary file of the updated version. The logically combining includes: applying an exclusive or operation; or applying an exclusive nor operation. The update file is built based on the mapping of the memory locations and on results of the logical combining.

  • Patent number: 11906994
    Abstract: A voltage regulator is embedded in a circuit intermediate a first node (coupled to a battery) and a second node (supplying power to an external memory). The voltage regulator is activatable in a first mode of operation for startup during which an voltage is applied to the second node that increases towards a supply threshold. In response to the voltage at the second node reaching the supply threshold, the voltage regulator transitions to a second mode of operation where a programmable regulated voltage (higher than the supply threshold) is applied to the second node. In response to receipt of a low-power operation request, a first high-drive regulator circuitry is deactivated and a second low-power regulator circuitry is activated to provide a third mode of operation at low power.
