Tip: 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.
