Abstract: A method of managing a non-volatile memory includes during a data writing process, selecting, by a program triggering the data writing process, an error detection and correction code from among two codes depending on a type of information being written. The information is written into the non-volatile memory, where the information is associated with the selected error detection and correction code.

Abstract: A method of verifying the atomicity of an operation of data update in an EEPROM, includes, during a data writing operation of writing the data, the steps of: initializing at least one first flag to a first value and storing this value in the EEPROM; erasing the data from the EEPROM; writing a value of the data into the EEPROM; and writing at least one second value of the first flag into the EEPROM.

Abstract: A flash memory management method, wherein: the data to be stored are organized in logic blocks; the memory is divided into pages; and each page is divided into frames, each frame being capable of containing at least one data block and at least one first frame metadata block containing all or part of the index values of the data block in an index tree, an index value corresponding to the address of a frame.

Abstract: A method includes storing data and metadata related to the data in logical words in a non-volatile memory. For each logical word stored in the non-volatile memory, a corresponding error-correction code is generated. Each physical word stored contains a logical word and the corresponding error-correction code. The metadata may contain atomicity information. The non-volatile memory may be a flash memory. Each physical word may contain a parity bit based on the logical word and the corresponding error-correction code stored in the physical word. The logical words may be encoded into physical words including the corresponding error correction code using an encoding table. The data and the metadata may be split into logical words.

Abstract: A counter is stored in a page of a flash memory having a plurality of pages. Header information is written to the page. The header information includes a first word containing a number of the page, a second word containing a first value of the counter, and a third word containing an initial error control code, which takes into account the first value of the counter. Counter information is written into frames of the selected page. The frames have a same number of words. Writing counter information into a frame includes writing a counter identifier that identifies the counter and a value independent from the counter identifier into the frame. A current value of the counter is determined based on the first value of the counter in the header data and frames of the selected page into which the counter information is written.

Abstract: A flash memory is divided into pages defining an erase granularity of the flash memory. A count value is written into page metadata. Each page is divided into frames. Each frame contains at least one data block and at least two frame metadata words including a first frame metadata word to store a block identifier. A current page is opened by incrementing the count value and writing the incremented count value into the at least one first page metadata word. The current page has its at least one first page metadata word containing a highest count value of the counter of the number of written pages. A logic data block is written into a selected frame and a block identifier of the logic data block is written into the first frame metadata word of the selected frame.

Abstract: A method of data storage in a non-volatile memory, wherein the non-volatile memory is divided into: a first region in which each page includes fields adapted to contain data and a field adapted to contain metadata; a second region in which each page includes fields adapted to contain data and a field adapted to contain metadata; a third region adapted to contain indicators of the progress of an operation in the first and second regions, the metadata fields of the first and second regions being respectively adapted to contain, during an operation of data update in a page of the first region, the indexes of a page in the second region and of said page of the first region.
