Abstract:
Address error detection including a method that receives write data and a write address, the write address corresponding to a location in a memory. Error correction code (ECC) bits are generated based on the received write data. The write data is transformed at a computer based on the write address and the write data, to produce transformed write data. The transforming is configured to cause an ECC to detect an address error during a read operation to the write address in response to a mismatch between either the write address or the read address and data read from the location. The transformed write data and the ECC bits are written to the location in memory.
