The advantages of having the In-DRAM ECC include some things that engineers would consider as absolute requirements. First, that the DRAM with ECC is drop-in compatible with non-ECC DRAMs. The electrical function, BGA footprint, and package size of the In-DRAM ECC component has to be compatible or it might be a non-starter. One of the significant benefits of the In-DRAM ECC is that this helps release processor or FPGA computing cycles, so more performance capacity might be unlocked. Using In-DRAM ECC requires fewer DRAMs, so this saves board space, and lowers the power consumption, compared the conventional approach, which has separate DRAM for the ECC bits.  Compared to systems without any ECC implementation, the In-DRAM solution has markedly lower error rates. As mentioned in the Oak Ridge server error rate study, 47 % of the errors were single bit errors, and both conventional ECC and In-DRAM ECC approaches routinely fix these kinds.
