Notes: 1. IDD specifications are tested after the device is properly initialized.
2. Input slew rate is specified by AC Input Test Condition.
3. IDD parameters are specified with ODT disabled.
4. Data bus consists of DQ, DM, DQS, /DQS, RDQS, /RDQS, LDQS, /LDQS, UDQS, and /UDQS. IDD
values must be met with all combinations of EMRS bits 10 and 11.
5. Definitions for IDD
L is defined as VIN ≤VIL (AC) (max.)
H is defined as VIN ≥VIH (AC) (min.)
STABLE is defined as inputs stable at an H or L level
FLOATING is defined as inputs at VREF = VDDQ/2
SWITCHING is defined as:
inputs changing between H and L every other clock cycle (once per two clocks) for address and control
signals, and inputs changing between H and L every other data transfer (once per clock) for DQ signals
not including masks or strobes.
6. Refer to AC Timing for IDD Test Conditions.
