Abstract
An apparatus includes encoding circuitry to generate code words for storage in a memory device. Decoding circuitry is responsive to a read transaction to decode one or more code words read from the memory device in order to generate read data for outputting in response to the read transaction. The decoding circuitry comprises error correction circuitry configured, for each read code word, to perform an error correction process to detect and correct errors in up to P symbols of the code word, where P is dependent on the number of ECC symbols in the code word. Error tracking circuitry determines error quantity indication data indicative of the errors detected by the error correction circuitry, and in response to the error quantity indication data indicating that an error threshold condition has been reached, the apparatus transitions from a normal mode of operation to a safety mode of operation.
