Abstract
An integrated circuit includes: a primary supply stage including a primary supply node, the primary supply stage being configured to deliver a primary supply voltage to the primary supply node; a secondary supply stage including a secondary supply node, the secondary supply stage being configured to deliver a secondary supply voltage to the secondary supply node; a supply-switching circuit; a pre-charging circuit controllably coupled to the secondary supply node via the supply-switching circuit; and a volatile memory circuit controllably coupled to the primary supply node and the secondary supply node via the supply-switching circuit, wherein the switching circuit is configured to connect a supply of the volatile memory circuit either to the primary supply node in a primary supply mode, or to the secondary supply node in a secondary supply mode.
