12.0 Input/Output Capacitance
[ Table 41 ] Input/Output Capacitance
Note :
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.
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_CTRL applies to ODT, CS and CKE
8. CDI_CTRL=CI(CTRL)-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,DM) - 0.5*(CIO(DQS)+CIO(DQS))
12. Maximum external load capacitance on ZQ pin: 5pF
