1) These values are not subject to production test but verified by device characterization.
2) Input capacitance is measured according to JEP147 procedure for measuring capacitance using a vector network analyzer. VDD, VDDQ
are applied and all other balls (except the ball under test) are floating. DQ’s should be in high impedance state. This may be achieved by
pulling CKE to low level.
3) Although DM is an input-only ball, it’s input capacitance models the input capacitance of the DQ and DQS balls.
