• Manufacturer Part Number: HYB18M1G320BF
• Description: DRAMs for Mobile Applications 1-Gbit x32 DDR Mobile-RAM
• Manufacturer: QIMONDA [Qimonda AG]

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
3) Although DM is an input-only ball, it’s input capacitance models the input capacitance of the DQ and DQS balls.

Parameter
Input capacitance: CK, CK
Delta input capacitance: CK, CK
Input capacitance: all other input-only balls
Delta input capacitance: all other input-only balls
Input/output capacitance: DQ, DQS, DM
Delta input/output capacitance: DQ, DQS, DM
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.
