Abstract:
The various embodiments described herein include circuits, methods and/or devices used to protect data in a storage device. In one aspect, a method includes performing a power fail operation on a first section of the storage device. The power fail operation includes supplying power, via an energy storage device, to the first section of the storage device, where the energy storage device is distinct from a power source used during normal operation of the storage device, and where supplying power via the energy storage device includes switching the output of the energy storage device from an output of a boost regulator to an input of the boost regulator. The power fail operation also includes performing data hardening on the first section of the storage device.
