Abstract
A flash storage device includes a power hold circuit including a double layer capacitor. A power source supplies power to the flash storage device and charges the double layer capacitor. The double layer capacitor supplies power for maintaining integrity of data during a data transfer occurring in the flash storage device when the power supplied by the power source is disrupted. Additionally, the flash storage device can inhibit subsequent data transfers until the power supplied by the power source is restored.
