Notes:
1. Although the DM, TDQS and TDQS pins have different functions, the loading matches DQ and DQS.
2. This parameter is not subject to production test. It is verified by design and characterization. The capacitance is
3. This parameter applies to monolithic devices only; stacked/dual-die devices are not covered here
4. Absolute value of C
5. The minimum C
6. Input only pins include: ODT, CS, CKE, A0-A15, BA0-BA2, RAS, CAS, WE.
7. CTRL pins defined as ODT, CS and CKE.
