Latest Patents

One of his latest patents is titled "Method and apparatus for error detection." This invention includes a memory buffer for storing user data contained in a data signal. It features a syndrome computer circuit that generates a plurality of EDC syndromes from an EDC codeword. The EDC codeword is encoded with a plurality of m-bit EDC parity symbols and n-bit ECC parity symbols to form the data signal, ensuring that m is greater than n. An ECC error correction circuit corrects the user data based on error signals generated for each corruption of the data signal. A completion signal is generated once the correction of the EDC codeword is complete. Additionally, a syndrome fix-up circuit adjusts the EDC syndromes based on the received error signals, allowing for the detection of miscorrections by the ECC error correction circuit.

Another notable patent is "PBA recovery apparatus and method for interleaved Reed-Solomon codes." This invention pertains to a method for determining if data read from a storage medium has been read from a physical block address (PBA) other than the expected PBA. The data stored on the medium is encoded according to a protocol that includes randomizing the data and combining it with a PBA string. When the data is read, it is decoded using a corresponding scheme. If errors exceed the error correction capacity, a second correction is performed by an error correction unit. If the error values in each interleave are consistent, a PBA error is presumed to be the source of the errors, allowing for the determination of the actual PBA from which the data was read.
