Abstract

Various embodiments relate to a memory controller configured to read data from a memory array, including: an error correction codes (ECC) encoder configured to encode data stored in the memory array; an ECC decoder configured to decode first data read from the memory array based upon a first read request and detect errors in the first data read from the memory array; and a fault controller configured to: command the memory controller to read other data from the memory array when the ECC detects an error; command the memory controller to re-read the first data from the memory array; when the ECC detects an error; compare the re-read first data to the read first data; and signal a fault attack when the re-read first data is different from the read first data.
