Notes:
1.
IDD specifications are tested after the device is properly initialized.
2.
Input slew rate is 1V/ns.
3.
Definitions for IDD:
LOW is defined as VIN ≤ 0.1 * VDDQ;HIGH is defined as VIN
≥ 0.9 * VDDQ;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.
IDD8 are typical value at 25℃.
