To maintain the … Web6 nov. 2024 · Single bit errors at data and ECC bits are correctable. Correctable errors are actually auto-corrected by hardware and the corrected data is returned back to the requestor (whoever made the read request to the physical page). However, actual corrupted data in the DRAM must be corrected from the software. WebThe side-band ECC scheme is typically implemented in applications using standard DDR memories (such as DDR4 and DDR5). As the name illustrates, the ECC code is sent as side-band data along with the actual data to memory. For instance, for a 64-bit data width, 8 additional bits are used for ECC storage. Hence, the DDR4 ECC DIMMs, commonly … thailand kennel club
