Memory device and method of controlling operation of the memory device

A memory device comprises a microcontroller, a error-tolerant repository with a rewritable section arranged to store program files and being associated with the microcontroller, and a memory array for storing data provided from an external source. A method for controlling operation of a memory device comprises receiving an event, loading a first program file stored in the memory array into a first section of the repository in response to the event, and executing the program file by the microcontroller in order to perform an operation of the memory device. The method and the device may advantageously be embodied in the field of flash memories.
