Notes:
1. These values are guaranteed by design.
2. These capacitance values are for package with single monolithic devices only. Multiple die packages will have parallel capacitive loads.
3. Although DM is an input-only pin, the input capacitance of this pin must model the input capacitance of the DQ and DQS pins. This is
required to match signal propagation times of DQ, DQS and DM in the system.
