WebThere are also a few motherboards that run triple-channel architecture. Triple-channel architecture also uses interleaving, which is a method of assigning memory addresses to the memory in a set order. For dual-channel architecture, the original design combined two 64-bit buses into a single 128-bit bus, which was later called the ganged model. WebDec 10, 2024 · The 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, …
