| 13 | description: | |
| 14 | The Nuvoton BMC SoC supports DDR4 memory with or without ECC (error correction |
| 15 | check). |
| 16 | |
| 17 | The memory controller supports single bit error correction, double bit error |
| 18 | detection (in-line ECC in which a section (1/8th) of the memory device used to |
| 19 | store data is used for ECC storage). |
| 20 | |
| 21 | Note, the bootloader must configure ECC mode for the memory controller. |
