A data storage device includes one or more non-volatile, blockwise erasable data storage media and a mechanism for sanitizing the media in response to a single external stimulus or in response to a predetermined physical or logical condition. Optionally, only part of the media is sanitized, at a granularity finer than the blocks of the medium. Setting a flag in an auxiliary nonvolatile memory enables an interrupted sanitize to be detected and restarted. Optionally, a 'death certificate' verifying the sanitizing is issued. Preferably, the media are configured in a manner that allows atomic operations of the sanitizing to be effected in parallel.

Methods of sanitizing a flash-based data storage device

A method executed by a circuit for counting electrons in storage cells in an array of at least two storage cells is provided. The method includes providing a storage array of at least two storage cells, and each of said at least two storage cells containing an unknown amount of electrons. A receiving array of at least two receiving cells is provided, where said at least two receiving cells initially contain no electrons. Then, extracting a layer of said electrons from said storage array of cells and inserting said layer into corresponding locations in said receiving array. The method then repeats said steps of extracting and inserting while at least one of said at least two storage cells is not empty. The method counts, for each said storage cell in said storage array, a productive-extraction amount.

Methods for interrupted counting of particles in cells

Methods and systems for counting items in storage containers in an array of at least two storage containers, the method including the steps of: providing a storage array of at least two storage containers, each of the storage containers containing an unknown amount of items; providing a receiving array of at least two receiving containers, wherein the receiving containers initially contain no items; extracting a layer of the items from the storage array; inserting the layer into corresponding locations in the receiving array; repeating the steps of extracting and inserting while at least one of the storage containers is not empty; counting, for each storage container in the storage array, a productive-extraction amount; and reporting, for at least some of the storage containers, the productive-extraction amount from each storage container. Preferably, the method further includes recovering a storage identity upon recovery from a system failure that erases the productive-extraction amount.
