Abstract: Approaches for a write assist circuit are provided. The write assist circuit includes a boost capacitor with a first node coupled to a bitline through control logic and a second node connected to a field effect transistor (FET) diode stack, a plurality of boot enabled transistors which each contain a gate connected to a boost control signal, and a controlled current source coupled between a ground signal and the second node of the boost capacitor. In the write assist circuit, the boost capacitor has a discharge path which is controlled to provide a boost voltage which is invariant to a level of a power supply signal.

Abstract: The present disclosure relates to mobile computing devices and, more particularly, to environmentally aware mobile computing devices and methods of use. The method is implemented in a computer infrastructure which has computer executable code tangibly embodied on a computer readable storage medium having programming instructions operable to: place a mobile computing device into a power savings mode when a environmental condition is below a sensor threshold value for a predetermined time period; and place the mobile computing device into a powered up state when the environmental condition exceeds the sensor threshold value.
