Data errors in non-volatile memory inevitably increase with usage and with higher density of bits stored per cell. The memory is configured to have a first portion operating with less error but of lower density storage, and a second portion operating with a higher density but less robust storage. Input data is written and staged in the first portion before being copied to the second portion. An error management provides checking the quality of the copied data for excessive error bits. The copying and checking are repeated on a different location in the second portion until either a predetermined quality is satisfied or the number or repeats exceeds a predetermined limit. The error management is not started when a memory is new with little or no errors, but started after the memory has aged to a predetermined amount as determined by the number of erase/program cycling its has experienced.

One embodiment of the present invention sets forth a technique for processing address page requests in a GPU system that is implementing a virtual memory model. A hardware-based page fault manager included in the GPU system intercepts page faults otherwise processed by a software-based page fault manager executing on a host CPU. The hardware-based page fault manager in the GPU includes a DMA engine capable of reading and writing pages between system memory and frame buffer memory without involving the CPU or operating system. A net improvement in system performance is achieved by processing a significant portion of page faults within the GPU, reducing the overall load on the host CPU.

A method and system for error management in a memory device. In one embodiment of the invention, the memory device can handle commands and address parity errors and cyclic redundancy check errors. In one embodiment of the invention, the memory can detect whether a received command has any parity errors by determining whether the command bits or the address bits of the received command has any parity errors. If a parity error or cyclic redundancy check error in the received command is detected, an error handling mechanism is triggered to recover from the errant command.

An error management system and process can be used to identify an erroneous data packet in a data stream. In response to identifying the erroneous data packet, a subsequent valid data packet is located in the data stream. In one embodiment, a plurality of candidate locations of header checksum windows are searched and checked for a valid checksum. Multiple integrity checks of multiple header checksums can be used to reduce the probability of a false positive integrity check. In another embodiment, one or more information data fields can used for determining packet integrity by determining if the fields contain valid information bits.

Data errors in non-volatile memory inevitably increase with usage and with higher density of bits stored per cell. The memory is configured to have a first portion operating with less error but of lower density storage, and a second portion operating with a higher density but less robust storage. An error management provides reading and checking the copy after copying to the second portion. If the copy has excessive error bits, it is repeated in a different location either in the second or first portion. The reading and checking of the copy is accelerated by reading only a sample of it. The sample is selected from a subset of the copy having its own ECC, where the sample selected depends on the count of erase-program cycles that a block has experienced, where different count ranges can use different samples.

A storage control apparatus of the present invention reduces the frequency of disk drive failures. An error management part manages the number of times errors occur in respective disk drives. A disk drive in which the number of errors meets or exceeds a threshold value is selected as a disk drive to be restarted. A restart control part commences difference management prior to restarting the disk drive targeted for restart. A difference management part manages parity group-related update locations using a difference bitmap. After commencing difference management, the restart control part restarts the disk drive in which the error was detected. This makes it possible to resolve an error caused by a firmware hangup or the like.

Techniques for dynamically measuring and monitoring error rate in Serializer/Deserializer (SerDes) links In one set of embodiments, a method includes polling a SerDes link status of a SerDes link at a predetermined rate. The method also includes storing a predetermined polling results in a memory, determining a number of polling results indicating one or more errors occurred in said SerDes link, determining an action to be taken if said number of polling results exceed a threshold.

To derive a Hamming code to manage data errors a set of at least four parity bit positions is selected for parity bits which will protect a set of data bits (where each data bit has a data bit position in the data bit set). A syndrome is determined for each data bit position. This involves selecting a unique sub-set of at least three parity bit positions. The unique sub-set shares at least one parity bit position with at least one other unique sub-set of at least three parity bit positions. A parity bit value may then be calculated for each parity bit position based on the determined syndromes. The header of a packet may be provided with a word which defines the length of the packet and an error management code generated utilizing this word so that errors in the word may be detected and, possibly, corrected.

Systems consistent with the present invention provide financial account management services for user service accounts. Such systems receive requests from users to register with a trusted intermediary. Registration with the intermediary enable users to customize management services to be performed for selected user service accounts. The trusted intermediary server periodically collects account information from provider servers that govern accounts provided to the users. The intermediary server then analyzes the collected account information to determine whether customized management services should be performed. The management services may include sending account status messages to the users and performing automatic payment functions to credit delinquent accounts. Such methods and systems enable users to avoid, for example, penalties and fees associated with mis-managed accounts by allowing the intermediary server to perform proxy management services for users.
