Abstract: Methods for data recovery and memory systems are provided. According to at least one such method, when defective data is read from a memory location, the data is recovered by an XOR operation on the remaining good data and associated RAID data to reconstruct the defective data. The defective data is excluded from the XOR operation.

Abstract: According to one embodiment, a group III-V semiconductor device comprises a compositionally graded body disposed over a substrate and below a buffer layer supporting an active area of the group III-V semiconductor device. The compositionally graded body includes a first region applying compressive stress to the substrate. The compositionally graded body further includes a stress modulating region over the first region, where the stress modulating region applies tensile stress to the substrate. In one embodiment, a method for fabricating a group III-V semiconductor device comprises providing a substrate for the group III-V semiconductor device and forming a first region of a compositionally graded body over the substrate to apply compressive stress to the substrate. The method further comprises forming a stress modulating region of the compositionally graded body over the first region, where the stress modulating region applies tensile stress to the substrate.

Abstract: Error correction in a disk drive is performed by error correction circuitry which accepts data read from a data storage medium. The error correction circuitry performs both block error correction in a first data domain and sector error correction in a second data domain. A sector FIFO buffer is used to facilitate the error correction in real time, or “on-the-fly.” The sector FIFO buffer also enables conversion of the corrected data to the first data domain. The error correction circuitry also generates an ECC block comprising a plurality of sectors and writes the ECC block. The circuitry generates a tag prior to writing the ECC block and adds the tag to each of a plurality of sectors. During a read operation, the circuitry detects a write disruption when the tags for all of the plurality of sectors in the ECC block are not identical.

Abstract: An integrated circuit chip that receives data on an asynchronous communications bus from an external device and receives data from asynchronous internal device is capable of switching from synchronous operation to asynchronous operation without any loss of data. The chip does not switch off the system clock while there is activity on the communications bus. Additionally, the communications bus has a minimum event time greater than the time fo one and a half cycles of the system clock plus enough timing margin for an asynchronous update to occur.

Abstract: A method and apparatus for protecting against overwrite and misread errors caused by cartridge movement is disclosed. The apparatus comprises a read/write head and a read-write protection switch in electrical communication with the read-write head wherein the read-write protection switch generates an electrical signal upon movement of the media cartridge that disables the read/write head. The method of misread and overwrite protection comprises: detecting movement of the cartridge shell; disabling read/write heads; identifying whether the media drive was in the process of reading from or writing to the media cartridge; if the media drive was writing to the storage medium when the cartridge shell is moved, generating a write fault interrupt; and if the media drive is reading from the storage medium when the cartridge shell is moved, generating a read fault interrupt. A removable media cartridge having a push member and an abutment surface is also disclosed.
