1. An electronic device, comprising:
a plurality of data storage cells, collectively operable in a data access mode and separately in a sleep mode, wherein the
sleep mode comprises a period of time during which the plurality of data cells are not accessed and during which a data state
stored in each cell in the plurality of data cells is to be maintained at a valid state; and
circuitry for providing at least one temperature-dependent voltage to at least one storage device in each cell in the plurality
of data storage cells during the sleep mode.
