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.

Second, the codes are typically 7 or 8 bits, which makes for an inefficient use of a 16-bit memory structure. This is handled by using the same memory chip for data and codes. This is referred to as “inline” ECC.
