ECC and DDR5
- Hamming Codes ECC RAM corrects errors that occur in memory before it gets to the CPU.
- The most common form of ECC is the Hamming Code [1] which when it has R redundant bits can correct single bit errors and detect double-bit errors in messages with 2^R-R-1 bits of data.
- For PC use that means if you want to protect 32bits of data you need R=6 and with 64bits you need R=7.
