Embodiments include but are not limited to apparatuses and systems including a microelectronic device including a gate, a source pad and a drain pad arranged such that the gate is separated from the source pad and the drain pad by air, and an insulating layer coupled with a portion of the gate such that at least a portion of the insulating layer is separated from the source pad and the drain pad by the air. Methods for making the same also are described.

RAID storage systems and methods adapted to enable the use of NAND flash-based solid-state drives. The RAID storage system includes an array of solid-state drives and a controller operating to combine the solid-state drives into a logical unit. The controller utilizes data striping to form data stripe sets comprising data (stripe) blocks that are written to individual drives of the array, utilizes distributed parity to write parity data of the data stripe sets to individual drives of the array, and writes the data blocks and the parity data to different individual drives of the array. The RAID storage system detects the number of data blocks of at least one of the data stripe sets and then, depending on the number of data blocks detected, may invert bit values of the parity data or add a dummy data value of “1” to the parity value.

摘要:
A non-volatile solid state memory-based mass storage device having at least one non-volatile memory component and methods of operating the storage device. In one aspect of the invention, the one or more memory components define a memory space partitioned into user memory and over-provisioning pools based on a P/E cycle count stored in a block information record. The storage device transfers the P/E cycle count of erased blocks to a host and the host stores the P/E cycle count in a content addressable memory. During a host write to the storage device, the host issues a low P/E cycle count number as a primary address to the content addressable memory, which returns available block addresses of blocks within the over-provisioning pool as a first dimension in a multidimensional address space. Changed files are preferably updated in append mode and the previous version can be maintained for version control.

A hydraulic fan drive includes a hydraulic pump that has an adjustable swept volume. The hydraulic pump is assigned a pressure control valve arrangement that is configured to regulate a pump pressure by adjustment of the swept volume. The drive further includes a hydraulic motor configured to drive an impeller wheel and a pressure line, which is connected to a pressure input of the hydraulic motor and into which pressure medium is configured to be conveyed by the hydraulic pump. A hydraulic accumulator is connected to the pressure line and the displacement of the hydraulic motor is configured to be adjusted. Energy is buffer-stored by the hydraulic accumulator by feeding in pressure medium beyond the amount that is displaced by the hydraulic motor. This stored energy becomes free for other operations of a machine, for example, to which the drive is attached.
摘要:
Non-volatile solid-state memory-based storage devices and methods of operating the storage devices to have low initial error rates. The storage devices and methods use bit error rate comparison of duplicate writes to one or more non-volatile memory devices. The data set with a lower bit error rate as determined during verification is maintained, whereas data sets with higher bit error rates are discarded. A threshold of bit error rates can be used to trigger the duplication of data for bit error comparison.

A nonvolatile storage device adapted for use with computers, workstations and other processing apparatuses. The storage device includes a printed circuit board, a nonvolatile memory array comprising at least two sub-arrays that contain nonvolatile solid-state memory devices, and control circuitry for interfacing with the processing apparatus. The control circuitry includes an abstraction layer and at least two memory control units configured to communicate data, address and control signals with the sub-arrays of the memory devices. A bus connects each memory control unit to a corresponding one of the sub-arrays. The control circuitry further includes a crossbar switch that functionally connects each memory control unit to the abstraction layer. The storage device is capable of overcoming limitations of current SSD designs by enabling independent read and write transfers (accesses) to the memory devices of the storage device, including concurrent read and write accesses.

A mass storage system comprising multiple memory cards, each with non-volatile memory components, a system bus interface for communicating with a system bus of a host system, and at least one ancillary interface. The ancillary interface is configured for direct communication of commands, addresses and data between the memory cards via a cross-link connector without accessing the system bus interface.

A biosignal-computer-interface apparatus and method. The apparatus includes one or more devices for generating biosignals based on at least one physiological parameter of an individual, and a computer-interface device capable of performing multiple tasks, including converting the biosignals into at least one input signal, establishing a scale encompassing different levels of the input signal, multiplying the input signal into parallel control channels, dividing the scale into multiple zones for each of the parallel control channels, assigning computer commands to each individual zone of the multiple zones, and generating the computer command assigned to at least one of the individual zones if the level of the input signal is within the at least one individual zone. The individual zones can be the same or different among the parallel control channels.

A NAND flash memory device and method of erasing memory cells thereof, wherein each cell is only subjected to the level of erase voltage needed to restore its nominal “erased” state. Each memory cell of the NAND flash memory device comprises a floating gate, a control gate connected to a wordline and receives a control voltage therefrom to induce a programming charge on the floating gate, and a bitline adapted to apply an erase voltage to deplete the floating gate of the programming charge. Each memory cell further includes circuitry for modulating the erase voltage according to the level of the programming charge on its floating gate.
