  • Publication number: 20100306448
    Abstract: A device, system and method in which data in a write cache, that must at some point be written to non-volatile memory, is written to non-volatile memory after expiration of a threshold time period during which no new host commands are received. If either the last dirty entry is written back or a host command is received during the write-back process, the time threshold time period and auto-flush process is restarted.

  • Publication number: 20100205513
    Abstract: Systems and methods for identifying error bits in encoded data are disclosed. As a part of identifying error bits, encoded data that is provided from a data source and that includes data and parity check portions is accessed. Based on the encoded data, syndromes are calculated, and based on the calculated syndromes, an equation is determined. The roots of the equation are determined and based on the determined roots of the equation, one or more error bits are identified. The error bits are identified using a circuit that presents a binary representation of the roots. The error bits are corrected based on the error bits that are identified.

  • Patent number: 7761740
    Abstract: Systems and/or methods that provide for the accuracy of address translations in a memory system that decouples the system address from the physical address. Address-modifying transactions are recorded in a non-volatile write buffer to couple the last-in-time translation physical address/location with the current translated physical location/address. In addition, integrity check protection may be applied to the translation and to the written data to limit the amount of data that may be lost in the event of a failure/error occurring during the write operation. Transaction recording and integrity check protection allows for recovery of write operations that may not have fully completed due to the failure/error.

  • Publication number: 20100122146
    Abstract: Providing for single and multi-bit error correction of electronic memory is described herein. As an example, error correction can be accomplished by establishing a suspect region between bit level distributions of a set of analyzed memory cells. The suspect region can define potential error bits for the distributions. If a bit error is detected for the distributions, error correction can first be applied to the potential error bits in the suspect region. By identifying suspected error bits and limiting initial error correction to such identified bits, complexities involved in applying error correction to all bits of the distributions can be mitigated or avoided, improving efficiency of bit error corrections for electronic memory.

  • Patent number: 7672161
    Abstract: Systems, methods, and/or devices that facilitate accessing data from memory are presented. An adaptive detection component can be employed to reduce or minimize detection error and distinguish information stored in memory cells during read operations. A decoder component can include the adaptive detection component, which can employ an adaptive Linde-Buzo-Gray (LBG) algorithm. The decoder component can receive information associated with a current level from a memory location during a read operation, and can analyze and process such information. The adaptive detection component can receive the processed information and, along with other information, can process such information using the iterative LBG algorithm until reconstruction levels and corresponding threshold levels are determined. Such reconstruction levels and/or threshold levels can be compared to the value associated with the information read from the memory location to determine the data value of the data in the memory location.

  • Patent number: 7524080
    Abstract: An illumination assembly comprises a base and at least one illumination cell. The base comprises a supply circuit for supplying an external power after connecting to a power source. The illumination cell is optionally connected to the base or removed from thereof, and includes a power storage unit stored with a storage power, a discharging circuit, and a charging circuit, wherein the power storage unit is electrically connected to the discharging circuit and the charging circuit. When the illumination cell is removed from the base, the storage power released from the power storage unit drives the illumination cell projecting an illumination light beam via the discharging circuit. When the illumination cell is assembled to the base, the supply circuit is electrically connected to the discharging circuit and the charging circuit respectively, so that the external power can drive the illumination cell projecting the illumination light beam and charge the power storage unit simultaneously.

  • Publication number: 20090106626
    Abstract: An accumulative repeat encoder can facilitate encoding data written to memory, such that parity data can be generated in accordance with a low-density parity-check (LDPC) code. The original data and associated parity data can be stored in memory. During a read operation, a decoder component can utilize the parity data based on the LDPC code to facilitate decoding the data being read from memory. The decoder component can be iterative and can provide one or more decoding results based on certain probability calculations as to the values of the read data. The decoder component can analyze a decoding result and reference a parity-check matrix structured in accordance with the LDPC code to determine the accuracy of the decoding result. If the decoding result attains a desired accuracy, the decoding result can be representation of the original data and can be provided as an output.

  • Patent number: 7362812
    Abstract: A channel tracking module, configured for generating updated equalization coefficients for a frequency equalizer, is configured for determining a digital-based error value between equalized signals output by the frequency equalizer relative to predicted signals, for each subcarrier frequency of an OFDM symbol. The channel tracking module determines an accumulated error based on accumulating the digital-based error values for all the subcarrier frequencies of the OFDM symbol, for a prescribed successive number of OFDM symbols. The channel tracking module also determines a step size based on the accumulated error and relative to a prescribed step function configured for optimizing equalizer adjustments within stability limits. The channel tracking updates the equalization coefficients for each subscarrier frequency based on the accumulated error and the step size.

  • Patent number: 7356108
    Abstract: A channel estimator is configured for determining a gain adjustment for a received wireless signal having a prescribed plurality of tones. The channel estimator is configured for generating, for each of the tones, a corresponding pseudo power value representing a detected power level for the corresponding tone. An accumulated pseudo power value is obtained based on accumulating the respective pseudo power values of the prescribed plurality of tones. Each of the pseudo power values is selectively adjusted by an adjustment factor based on a determined difference between the accumulated pseudo power value relative to an expected accumulated power level relative to a prescribed dynamic range. The pseudo power values are then output for decoding of data modulated at the respective tones.

An oxide liner is formed on the exposed sidewall portion. A recess may be formed in the buried insulator layer (prior to forming the first layer) and may extend partially beneath the patterned silicon layer.
