摘要： Systems and methods are provided that confront the problem of failed storage integrated circuits (ICs) in a solid state drive (SSD) by using a fault-tolerant architecture along with one error correction code (ECC) mechanism for random/burst error corrections and an L-fold interleaving mechanism. The systems and methods described herein keep the SSD operational when one or more integrated circuits fail and allow the recovery of previously stored data from failed integrated circuits and allow random/burst errors to be corrected in other operational integrated circuits. These systems and methods replace the failed integrated circuits with fully functional/operational integrated circuits treated herein as spare integrated circuits. Furthermore, these systems and methods improve I/O performance in terms of maximum achievable read/write data rate.

摘要： A mechanism is provided for controlling a solid state storage device in which the solid state storage comprises erasable blocks each comprising a plurality of data write locations. Input data is stored in successive groups of data write locations, each group comprising write locations in a set of erasable blocks in each of a plurality of logical subdivisions of the solid state storage. The input data is error correction encoded such that each group contains an error correction code for the input data in that group. Metadata, indicating the location of input data in the solid state storage, is maintained in memory. An indication of validity of data stored in each data write location is also maintained. Prior to erasing a block, valid input data is recovered from the or each said group containing write locations in that block. The recovered data is then re-stored as new input data.

摘要： A system, method apparatus, and computer readable medium for managing renewal of a dynamic set of data items. Each data item has an associated renewal deadline, in a data item management system. A renewal schedule allocates to each data item a renewal interval for renewal of the data item. On addition of a new data item, if a potential renewal interval having a duration required for renewal of the data item, and having an ending at the renewal deadline for that item does not overlap a time period in the schedule during which the system is busy, the renewal schedule is automatically updated by allocating the potential renewal interval to the new data item. If the potential renewal interval does overlap a busy period, the renewal schedule is automatically updated by selecting an earlier renewal interval for at least one data item in the set.
