ICC specication is based on
SAMSUNG components. Other DRAM manufactures specication may be different.
Note:
* Value calculated as one module rank in this operating condition, and all other module ranks in ICC2P (CKE LOW) mode.
** Value calculated reects all module ranks in this operating condition.
