2. For data signal, input slew rate
3. For data signal, input slew rate
4. For CK and CK# signals, input slew rates are
DIMMs. These are meant to be a subset of the parameters for the specific device used on the module. Detailed
information on this part has been shown at the JEDEC JC-40 Committee. Please contact Micron Technology's Module
Applications Team if further information on the specific register model is required.
