A method for managing the consumption of a memory device includes performing a first reading of data in a first portion of a first memory area of the memory device. During a same memory access, error correction code check bits are read from a second portion of a second memory area of the memory device. The error correction check bits include error correction check bits that are associated with the data in the first portion of the first memory area and other error correction code check bits associated with other data. All of the other error correction code check bits are stored in a register, and the other data in the first portion of the first memory area is read. The error correction code bits associated with the other data are extracted from the register.

Method for managing the consumption of a memory device when using an error-correction code and corresponding system

A system includes a control unit configured to be electrically connected to an input of a memory via a communication interface. The control unit includes a first power supply sector configured to be powered when the control unit is in an operating mode and a second power supply sector configured to be powered when the control unit is in the operating mode and in a low consumption mode. In the first power supply sector, the control unit includes a first configuration circuit operating to configure a polarization value of the input of the memory via the communication interface for the operating mode. In the second power supply sector, the control unit includes a second configuration circuit operating to configure a polarization value of the input of the memory via the communication interface for the low consumption mode.

Electronic system comprising a control unit configured to communicate with a memory

Embodiments described in the present disclosure relate to a method for initializing registers of peripherals of a microcontroller, including acts of: accessing initialization data in a non-volatile memory connected by a main bus to a processing unit of the microcontroller and to the peripherals, activating a peripheral including registers to be initialized, and transferring the data read into the registers of the activated peripheral, the initialization data being accessed in the memory by an initialization circuit distinct from the processing unit, the initialization data accessed being sent to the peripherals by an initialization bus distinct from the main bus.
