Abstract
An integrated circuit device includes low voltage internal circuitry and a first external pin which receives a first information signal. The first information signal provides operating information within a predetermined voltage range. The device includes a mode detector coupled to the first external pin. The mode detector provides a mode enable signal in response to the first information signal being at a voltage that is outside the predetermined voltage range. The device further includes a switchable regulator which provides a supply voltage to the low voltage internal circuitry to power the low voltage internal circuitry at a regulated voltage in a normal mode of the integrated circuit memory and at a higher voltage than the regulated voltage in response to the mode enable signal.
