Abstract
A system includes a memory formed by memory units accessible in write mode and in read mode. Each memory unit includes an array of memory cells and a peripheral circuit of access to the memory cells. Each memory unit is configurable in a first operating mode and a second operating mode. The array of memory cells are set in the first operating mode and the second operating modes to retain data until a subsequent powering off of the memory unit. The peripheral circuit is powered in the first operating mode and is not powered in the second operating mode. A controller configures any memory unit of the memory having undergone no write or read access for a determined time period to be in the second operating mode.
