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



measured according to JEP147(“PROCEDURE FOR MEASURING INPUT CAPACITANCE USING A VECTOR NETWORK



ANALYZER(VNA)”) with VDD, VDDQ, VSS,VSSQ applied and all other pins floating (except the pin under test, CKE,



RESET and ODT as necessary). VDD=VDDQ=1.5V, VBIAS=VDD/2 and on-die termination off.

3. This parameter applies to monolithic devices only; stacked/dual-die devices are not covered here

4. Absolute value of CCK-CCK.

5. Absolute value of CIO(DQS)-CIO(DQS).

6. CI applies to ODT, CS, CKE, A0-A15, BA0-BA2, RAS, CAS, WE.

7. CDI_CTR applies to ODT, CS and CKE.

8. CDI_CTRL=CI(CNTL) - 0.5 * CI(CLK) + CI(CLK))

9. CDI_ADD_CMD applies to A0-A15, BA0-BA2, RAS, CAS and WE.

10. CDI_ADD_CMD=CI(ADD_CMD) - 0.5*(CI(CLK)+CI(CLK))

11. CDIO=CIO(DQ) - 0.5*(CIO(DQS)+CIO(DQS))

12. Maximum external load capacitance an ZQ pin: 5 pF.
