Abstract: A storage system includes a controller that is configured to make host data inaccessible. To do so, the controller may control power control circuitry to supply pulses to storage locations storing host data. The pulses may include flash write pulses but no erase pulses, or a combination of flash write pulses and erase pulses. If erase pulses are supplied, the number of the erase pulses may be less than the number supplied for performance of a default erase operation.
