Notes1.
VDD, VDDQ, VSS, VSSQ applied and all other pins (except the pin under test) floating. VDD = VDDQ
=1.5V, VBIAS=VDD/2.
Notes2.
Absolute value of CCK(CK-pin) - CCK(/CK-pin).
Notes3
. CCK (min.) will be equal to CIN (min.)
Notes4.
CDIN_CTRL = CIN_CTRL - 0.5*(CCK(CK-pin) + CCK(/CK-pin))
Notes5
. CDIN_ADD_CMD = CIN_ADD_CMD - 0.5*(CCK(CK-pin) + CCK(/CK-pin))
Notes6.
Although the DM, TDQS and /TDQS pins have different functions, the loading matches DQ and DQS.
Notes7.
DQ should be in high impedance state.
Notes8.
CDIO = CIO (DQ, DM) - 0.5*(CIO(DQS-pin) + CIO(/DQS-pin)).
Notes9.
Maximum external load capacitance on ZQ pin is 5pF.
Notes10.
Absolute value of CIO(DQS) - CIO(/DQS).
