Abstract
Various implementations described herein relate to systems and methods for detecting soft errors, including but not limited to, errors introduced after reading a codeword from a non-volatile memory, and before providing data to a host. Embodiments can include decoding the codeword from the non-volatile memory to obtain at least input data, and determining validity of the input data using a first signature after processing the input data through a data path. If it is determined that the input data is valid using the first signature, the input data is sent to a host.
