摘要:
A storage device includes a host interface, a buffer memory, a storage medium, and a controller. The host interface is configured to receive storage data and an invalidation command, where the invalidation command is indicative of invalid data among the storage data received by the host interface. The buffer memory is configured to temporarily store the storage data received by the host interface. The controller is configured to execute a transcribe operation in which the storage data temporarily stored in the buffer memory is selectively stored in the storage medium. Further, the controller is responsive to receipt of the invalidation command to execute a logging process when a memory capacity of the invalid data indicated by the invalidation command is equal to or greater than a reference capacity.

A data storage device includes a storage medium and a controller circuit configured to be coupled to an external host to provide an interface between the external host and the storage medium, the controller circuit configured to detect a virus carried by a data file transferred to and/or stored in the storage medium. The controller circuit may be further configured to cure the detected virus.

摘要:
An encryption/decryption method of an endecryptor including a plurality of endecryption units supporting an XES mode with tweak and ciphertext streaming (XTS) includes dividing an input data stream into consecutive data units; inputting the divided data units to the endecryption units, respectively; and simultaneously processing the input data units at the respective endecryption units. According to the encryption/decryption method, parallel processing is performed to encrypt/decrypt data at higher speed.
摘要:
A method and apparatus for vacuum processing of a workpiece, the apparatus including a flow equalizer disposed in a vacuum processing chamber between a workpiece support pedestal and a pump port located in a wall of the vacuum processing chamber. In an embodiment, the flow equalizer has a first annular surface concentric about the workpiece support pedestal to provide conductance symmetry about the workpiece support even when the pump port is asymmetrically positioned within the vacuum processing chamber. In an embodiment, the flow equalizer has a second annular surface facing a lower surface of the workpiece support pedestal to restrict conductance as the flow equalizer is moved is response to a chamber pressure control signal. In an embodiment, the apparatus for vacuum processing of a workpiece includes tandem vacuum processing chambers sharing a vacuum pump with each tandem chamber including a flow equalizer to reduce cross-talk between the tandem chambers.
摘要:
Methods of depositing a protective coating of a silicon-containing or metallic material onto a semiconductor substrate include sputtering such material from an electrode onto a semiconductor substrate in a plasma processing chamber. The protective material can be deposited onto a multi-layer mask overlying a low-k material and/or onto the low-k material. The methods can be used in dual damascene processes to protect the mask and enhance etch selectivity, to protect the low-k material from carbon depletion during resist strip processes, and/or protect the low-k material from absorption of moisture.
