- DIN[71:0] with double-bit error injected is written into the memory array.
- When the memory location is accessed, the corrupted data is read out and a double-bit error is detected.
- DBITERR lines up with the corresponding DOUT data.
The ECC decoder also detects when double-bit errors in parity bits occur, and when a single-bit error in the data bits and a single-bit error in the corresponding parity bits occurs.
