Abstract: The integrity of a memory is checked by: storing data representative of an operation to be executed in the memory; executing the operation; and erasing the data once the execution is complete.

Abstract: A memory chip includes at least two memory blocks. In a method for controlling power supply for the memory blocks of the memory chip, each memory block receives a command for switching to standby mode. The commands are issued, for example by a processor, separately for each memory block in order to be able to individually place the memory block in standby mode.

Abstract: An error-correction code memory includes memory locations for storing data. The memory is programmed to store one or more intentionally invalid words. Testing of an error correction circuit for the memory is performed by accessing the one or more intentionally invalid words and performing an error detection and error correction operation.

Abstract: A device includes first and second buffers fillable with contents of memory locations. A selection circuit is configured to select a filling mode between simultaneous filling of the buffers and sequential filling of the buffers. In some examples, the device can be a system on a chip that includes a non-volatile memory and a processor.

Abstract: In an embodiment a method for operating an integrated circuit includes sequentially requesting, by a processor of an integrated circuit, different instruction lines; determining, by a first comparator of the integrated circuit, while the processor processes a current instruction line supplied in response to a corresponding request, whether or not at least one of the instructions of the current instruction line is a branch instruction by comparing the at least one of the instructions to reference instructions; executing, by the processor, all instructions of the current instruction line before executing a next instruction line when the at least one instruction is a branch instruction from a program memory of the integrated circuit; and executing, by the processor, all instruction of the current instruction line before executing a next instruction line from first and second volatile memory of the integrated circuit when the at least one instruction is not a branch instruction.
