| Normal (DDRMC0) | Flipped (DDRMC1) | |
|---|---|---|
| First bank (lowest number) | M0P0-31, Half Bank H0 | M1P64-95, Half Bank H1 |
| Second bank | M0P32-63, Half Bank H1 | M1P32-63, Half Bank H0 |
| Third bank (highest number) | M0P64-95, Half Bank H0 | M1P0-31, Half Bank H1 |
Important: The same signal (for example,
dq[0]) always maps to the **same M\*P\*
position** on both Normal and Flipped DDRMCs. The difference is
which physical bank that M*P* position falls in.Adjacent DDRMCs in the device alternate between Normal and Flipped bank mappings.
