The parity mode uses 1 parity bit for each byte, normally it is even parity mode, that is, each time
the memory data is updated, parity bit will be adjusted to have even count "1" for each byte. When
next time, if memory is read with odd number of "1", the parity error is occurred and this is called
single bit error detection.
