A memory device configurable for independent double gate cells, storing multiple bits per cell, includes multilayer stacks of conductive strips configured as word lines. Active pillars are disposed between pairs of first and second stacks, each active pillar comprising a vertical channel structure extending from an underlying bounded conductive layer, a charge storage layer and an insulating layer. The insulating layer in a frustum of an active pillar contacts a first arcuate edge of a first conductive strip in a layer of the first stack and a second arcuate edge of a second conductive strip in a same layer of the second stack. The conductive strips can comprise a metal. The active pillar can be generally elliptical with a major axis parallel with the first and second conductive strips.

Systems and methods for providing accelerated data storage and retrieval utilizing lossless data compression and decompression. A data storage accelerator includes one or a plurality of high speed data compression encoders that are configured to simultaneously or sequentially losslessly compress data at a rate equivalent to or faster than the transmission rate of an input data stream. The compressed data is subsequently stored in a target memory or other storage device whose input data storage bandwidth is lower than the original input data stream bandwidth. Similarly, a data retrieval accelerator includes one or a plurality of high speed data decompression decoders that are configured to simultaneously or sequentially losslessly decompress data at a rate equivalent to or faster than the input data stream from the target memory or storage device. The decompressed data is then output at rate data that is greater than the output rate from the target memory or data storage device. The data storage and retrieval accelerator method and system may employed: in a disk storage adapter to reduce the time required to store and retrieve data from computer to disk; in conjunction with random access memory to reduce the time required to store and retrieve data from random access memory; in a display controller to reduce the time required to send display data to the display controller or processor; and/or in an input/output controller to reduce the time required to store, retrieve, or transmit data.

The invention discloses a method for hiding light-weight files under an NTFS file system, which belongs to the technical field of computer network information. The method comprises a data hiding method and a hidden data recovering method, wherein, the data hiding method is characterized in that metadata of the file system referred according to the legal file path traverses index record entries of special files, thereby achieving the purpose of hiding file data. The hidden data recovering method is characterized in that the hidden data is redisplayed and added into the file system by altering the index record entry of a temporary file according to the legal file path and the record number of the hidden files, thereby achieving the purpose of recovering the hidden data. By adopting the invention, the confidentiality of confidential data and the transparency for other users can be realized through data hiding. Meanwhile, data exchange and operation expenditure during the execution process of hidden data are minimized, and data integrity and reliability are protected to the greatest extent.

A method for managing a data storage system includes maintaining a record predictive of locations to which data are to be written on a first storage medium by a host computer. Upon receiving a write command from the host computer directed to storing specified data at a specified location on the first storage medium, if the specified location is not included in the record, the record is updated responsively to the specified location. A signal is sent to the host computer that the specified data have been stored in the data storage system responsively to storing the specified data and, if the specified location was not included in the record, responsively to updating the record. The specified data are copied to the second storage medium responsively to the record, and are stored in the specified location on both the first and second storage media.

The possibility of the loss of information stored in a memory cell which is caused by repeating the reading action on the same memory cell comprising a variable resistance element and a select transistor can significantly be reduced. A voltage applying circuit for selecting one or more of the memory cells from a memory cell array and applying voltages to the word lines, bit lines, and source lines for programming, erasing, and reading information applies a voltage between the bit line and the source line connected to the selected memory cell so that the voltage applied between the two ports of the variable resistance element in the selected memory cell during the reading action is equal in the polarity to one of the voltages applied between the two ports of the variable resistance element for the programming action and the erasing action respectively whichever is greater in the absolute value.

A suspension assembly elastically biasing a slider toward a surface of a disk, in which a read/write head is mounted on the slider. In the suspension assembly, a load beam is coupled to a first portion of a swing arm of the actuator. A flexure supports the slider and has a first end portion fixed to a disk facing surface of the load beam and a second end portion extended toward a first end portion of the load beam. An end-tab is extended from the first end portion of the load beam. When the head is parked, the end-tab is supported by a ramp, which is arranged at an outside of the disk.

A data storage device with improved data storage densities, coupled with lower hard error and write-inhibit events is described. A feed-forward write inhibit (FFWI) method enables data tracks to be written more densely. Alternatively, the FFWI method may reduce the hard error and write inhibit events to improve data storage performance. A concept of virtual tracks enables the FFWI method to be applied to the writing of circular data tracks with non-circular servo tracks, or to the writing of non-circular data tracks with PES data from circular servo tracks—in both cases, improvements to performance and/or storage densities are enabled. The FFWI method may also be applied to the case of both non-circular servo and data tracks.
