Abstract:
Disclosed herein is a method of operating a non-volatile static random access NVSRAM memory formed from words. Each word includes NVSRAM cells, each of those NVSRAM cells having an SRAM cell and an electronically erasable programmable read only memory EEPROM cell. If the SRAM cells of a word have been accessed since powerup, data is read from the NVSRAM cells of that word through the SRAM cells. However, if the SRAM cells of that word have not been written since powerup, data is read from the NVSRAM cells of that word through the EEPROM cells.

An electromagnetic transponder including a resonant circuit; a rectifying bridge having input terminals connected across the resonant circuit and having rectified output terminals providing an electronic circuit power supply voltage; and a device for limiting the voltage across the resonant circuit, connected between the input terminals of the rectifying bridge.
Abstract:
A method of programming an EEPROM, including: a first mode where a writing into cells is performed under a first voltage; and a second mode where the writing is performed under a second voltage smaller than the first one.

Abstract:
A communication system includes an I2C bus interconnecting at least one first device and one second device. At least one direct data link, other than the I2C bus, interconnects the first and second devices. The system is configurable to operate in: a first operating mode providing for data only transmission between the first and second devices over the I2C bus; and a second operating mode providing for simultaneous data transmission between the first and second devices over both the I2C bus and said data link.
Abstract:
Method for processing a non-volatile memory designed to store words containing data bits and control bits allowing an error correction with an error correction code, the method comprising the storage of information in the memory plane comprising an operation for writing in the memory plane at least one digital word modified with respect to at least one initial digital word not having any erroneous bit, said at least one modified digital word containing a bit having a modified value with respect to the value of this bit in said at least one initial digital word, the other bits of the modified digital word having values identical to those of these same bits in the initial digital word, the position of the modified bit in said at least one modified digital word defining the value of the digital information.
