Storage device, electronic device, and data error correction method
Abstract:
According to one embodiment, a storage device includes an error detector, a check module, and a replacement module. The error detector detects a bit error that occurs in entry data related to conversion to a physical address corresponding to a logical address based on an error detecting code assigned to the entry data. The check module checks, based on data obtained by inverting one bit among all bits of the entry data and on data read out from the physical address indicated by the obtained data, whether or not the obtained data is normal entry data. The replacement module replaces the entry data where the bit error is detected with the checked normal entry data.
