Notes: 1. All voltages referenced to VSS.
2. Tests for IDD characteristics may be conducted at nominal supply voltage levels, but the
related specifications and device operation are guaranteed for the full voltage range
specified.
3. Timing and IDD tests may use a VIL-to-VIH swing of up to 1.5V in the test environment,
but input timing is still referenced to VDDQ/2 (or to the crossing point for CK/CK#). The
output timing reference voltage level is VDDQ/2.
4. IDD is dependent on output loading and cycle rates. Specified values are obtained with
minimum cycle time with the outputs open.
5. IDD specifications are tested after the device is properly initialized and values are aver-
aged at the defined cycle rate.
6. MIN (tRC or tRFC) for IDD measurements is the smallest multiple of tCK that meets the
minimum absolute value for the respective parameter. tRAS (MAX) for IDD measure-
ments is the largest multiple of tCK that meets the maximum absolute value for tRAS.
7. Measurement is taken 500ms after entering into this operating mode to provide settling
time for the tester.
8. VDD must not vary more than 4% if CKE is not active while any bank is active.
9. IDD2N specifies DQ, DQS, and DM to be driven to a valid high or low logic level.
10. CKE must be active (HIGH) during the entire time a REFRESH command is executed.
From the time the AUTO REFRESH command is registered, CKE must be active at each
rising clock edge until tRFC later.
11. This limit is a nominal value and does not result in a fail. CKE is HIGH during REFRESH
command period (tRFC [MIN]) else CKE is LOW (for example, during standby).
12. Values for IDD6 85C are guaranteed for the entire temperature range. All other IDD6 val-
ues are estimated.
13. Typical values at 25C, not a maximum value.
