Abstract: An apparatus and method for correcting errors in data accessed from a memory device. A plurality of read symbols are read from a memory device. Syndrome information is then determined from the n data symbols and associated m error correction code symbols. Error correction circuitry uses the syndrome information in order to attempt to locate each read symbol containing an error and to correct the errors in each of those located read symbols. Error tracking circuitry tracks which memory regions the located read symbols containing an error originate from, and, on detecting an error threshold condition, sets at least one memory region as an erasure memory region. The correction circuitry treats each read symbol as a located read symbol containing an error, such that the read symbols to be located are not all randomly distributed and more than PMAX read symbols containing errors can be corrected.

Abstract: A data processing apparatus having a memory configured to store tables having virtual to physical address translations, a cache configured to store a subset of the virtual to physical address translations and cache management circuitry configured to control transactions received from the processor requesting virtual address to physical address translations. The data processing apparatus identifies where a faulting transaction has occurred during execution of a context and whether the faulting transaction has a transaction stall or transaction terminate fault. The cache management circuitry is responsive to identification of the faulting transaction having a transaction terminate fault to invalidate all address translations in the cache that relate to the context of the faulting transaction such that a valid bit associated with each entry in the cache is set to invalid for the address translations.
