DDR Data Swizzling
9 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 OS/SW.
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.
