Embedded systems and methods of reading or writing data or instructions of at least one application in a non-volatile memory are disclosed. A method includes reading or writing data or instructions of at least one application in a non-volatile memory of an embedded system. The data or instructions transit through a memory area and are interpreted by a distinct program of an operating system of the embedded system.

Embedded system

Embedded systems and methods of starting an embedded system are disclosed. A method of starting an embedded system includes executing first instructions, distinct from instructions of an operating system of the embedded system. The method further includes causing the storage of at least one application into a non-volatile memory in response to executing the first instructions.

The present description relates to a method and a circuit for powering a volatile memory in which power pulses are sent to the memory, the duration between two pulses being shorter than a remanence time of said volatile memory.

A method of wireless communication between a transponder and a terminal includes a step, implemented by the transponder, of counting a number of error signals transmitted by the terminal.

The disclosure concerns a flash memory interface having a memory management unit including a comparator configured to determine whether an address of a flash memory access operation corresponds to a logical address or a physical address by comparing the address with one or more address ranges and a logical memory unit configured to convert logical addresses into physical addresses and to provide the physical addresses to the flash memory. The memory management unit is configured to direct physical addresses to the flash memory and to direct logical addresses to the logical memory unit for conversion into physical addresses.

Logical memory unit for flash memory

Data is stored in a non-volatile memory during an off-line transaction between a circuit containing memory and a terminal. A page of the memory is assigned to each transaction, and the data of each transaction is stored sequentially in the corresponding page. The page assigned to each transaction is locked in a write mode at the end of the corresponding transaction.

Data storage in a flash memory

A first near-field communication device is configured according to a modulation type transmitted by a second device. A decoder of the first device decodes a received signal using type-A modulation during a first time slot corresponding to the duration of a first type-A symbol. The first device determines the modulation type transmitted by the second device according to the value of the decoded symbol.

Configuration of a near-field communication router according to the modulation type

A method of updating a counter in a flash memory includes a first phase where a set of values capable of being taken by the counter are programmed in at least one page of the flash memory. A second phase of updating the counter programs a state zero in the flash memory each time the counter is incremented/decremented.
