Abstract
An apparatus to pre-condition an operating integrated circuit (IC) device in a static low power retention state. The apparatus includes a pseudo random number generator that generates a pseudo random number value to pre-condition the static low power retention state of the operating IC device. The apparatus also includes a controller that drives the pseudo random number value into a test scan chain linking logic elements of the operating IC device responsive to the operating IC device entering a sleep mode. Driving the pseudo random number value into the test scan chain by the controller places the operating IC device into the static low power retention state.
