DDR Data Swizzling
To achieve better memory performance and better memory timing, Intel design 
performed the DDR Data pin swizzling that will allow 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. This chapter 
presents swizzling data. When placing a DIMM logic analyzer, the design engineer must 
pay attention to the swizzling table to perform an efficient memory debug.
