US Patent 7523379 Method for time-delayed data protection

A method is provided for time-delayed data protection. During a writing operation, data is written to a register file, an error correction code is computed, and a delayed write of the error correction code to the register file is performed. Additionally, during a reading operation, data is read and if the error correction code is in the register file, the error correction code is read and the data is checked using the error correction code. If the error correction code is not in the register file, the data from the register is read without checking the data using the error correction code.
