Notes:
1. VDD = 1.8 V
± 0.1V; VDDQ = 1.8 V± 0.1V.
2. IDD specifications are tested after the device is properly initialized.
3. Input slew rate is specified by AC Parametric Test Condition.
4. IDD parameters are specified with ODT disabled.
5. Data Bus consists of DQ, LDM, UDM, LDQS, LDQS , UDQS and UDQS .
6. Definitions for IDD
LOW = Vin ≦ VIL (ac) (max)
HIGH = Vin ≧ VIH (ac) (min)
STABLE = inputs stable at a HIGH or LOW level
FLOATING = inputs at VREF = VDDQ/2
SWITCHING = inputs changing between HIGH and LOW every other clock cycle (once per two clocks) for address and
control signals, and inputs changing between HIGH and LOW every other data transfer (once per clock)
for DQ signals not including masks or strobes.
