Abstract: A method of performing an atomic write command in a data storage device comprising a volatile memory and a plurality of non-volatile memory devices configured to store a plurality of physical pages. The method may comprise storing data in a plurality of logical pages (L-Pages), each associated with a logical address. A logical-to-physical address translation map may be maintained in the volatile memory, and may be configured to enable determination of a physical location, within one or more of the physical pages, of the data referenced by each logical address. The data specified by a received atomic write command may be stored one or more L-Pages. Updates to the entry or entries in the translation map associated with the L-Page(s) storing the data specified by the atomic write command may be deferred until all L-Pages storing data specified by the atomic write command have been written in a power-safe manner.

The primary door includes a first end, a second end, and a wall extending between the first end and the second end. The primary door defines an opening in the airflow door assembly. The sub-door is pivotably mounted to the primary door and is movable between a closed position and an open position. In the closed position the sub-door is seated within the opening to restrict airflow through the opening. In the open position the sub-door is rotated out from within the opening to permit airflow through the opening.

Abstract: Methods for forming useful films using recombinant spider silk protein are discussed. In one embodiment, the method involves dissolving silk protein in a sufficient quantity to form a film suspended in a solvent. The solution is then mixed with a compound selected from water, acids, imidazole crosslinking agents, antibiotics, nanoparticles, surfactants and combinations thereof. Solubilisation of the protein in the solution is effected by microwave exposure. Once solubilized the microwave treated solution is poured onto a suitable substrate and dried in order to result in the final film, the protein may be plant, mammal or bacterially derived.

The array may comprise a plurality of S-Pages that may each comprise a plurality of F-Pages. In turn, each of the plurality of F-Pages may be configured to store a variable amount of data and a variable amount of error correction code.

Abstract: A data storage system configured to implement a data reliability scheme is disclosed. In one embodiment, a data storage system controller detects uncorrectable errors using intra page parity when data units are read from a set of pages. When an uncorrectable error is detected, the data storage system controller attempts to recover user data using inter page parity without using all data from each page of the set of pages. Recovery of user data can thereby be performed without reading all data from each page. As a result, the amount of time needed to read data can be reduced in some cases and overall data storage system performance can be increased.

Abstract: A secure data storage system includes a mechanism that can be activated to inhibit access to stored data. In one embodiment, access to stored data can be prevented without having to erase or modify such data. An encryption key, or data used to generate the encryption key, is stored in an MRAM module integrated within the data storage system. The data storage system uses the encryption key to encrypt data received from a host system, and to decrypt the encrypted data when it is subsequently read by a host system. To render the stored data inaccessible, an operator (or an automated process) can expose the MRAM module to a magnetic field of sufficient strength to erase key data therefrom.
