Abstract
Solid-state mass storage devices and methods of operation thereof include a solid-state mass storage device that may have a capacitor-based power supply module configured for providing power to the mass storage device. In one embodiment, the mass storage device has a first mode of operation wherein a primary power supply provided by a host system provides power to the mass storage device sufficient for its operation and provides power to the capacitor-based power supply module to recharge the module, and a second mode of operation wherein power is provided to the mass storage device from both the primary power supply and the capacitor-based power supply module. The mass storage device may be capable of providing power from the capacitor-based power supply module to the mass storage device after a voltage level of the capacitor-based power supply module falls below an under voltage lock out level.
