DDR Data Swizzling
9 DDR Data Swizzling
To achieve better memory performance and timing, Intel Design performed DDR Data
pin swizzling that allows a better use of the product across different platforms.
Swizzling has no effect on functional operation and is invisible to the operating
system/software.
However, during debug, swizzling needs to be taken into consideration. Therefore,
swizzling information is presented in this chapter. When placing a DIMM logic analyzer,
the design engineer must pay attention to the swizzling table in order to be able to
debug memory efficiently.
