1) IDD specifications are tested after the device is properly initialized and measured at 133 MHz for -7.5 speed grade.
2) Input slew rate is 1.0 V/ns.
3) Definitions for IDD:
LOW is defined as VIN ≤ 0.1 * V_DDQ;
HIGH is defined as VIN ≥ 0.9 * V_DDQ;
STABLE is defined as inputs stable at a HIGH or LOW level;
SWITCHING is defined as:
- address and command: inputs changing between HIGH and LOW once per two clock cycles;
- data bus inputs: DQ changing between HIGH and LOW once per clock cycle; DM and DQS are STABLE
4) All parameters are measured with no output loads.
5) I_DD8 value shown as typical
