Electrical Specifications – IDD Specifications and Conditions
Within the following IDD measurement tables, the following definitions and conditions
are used, unless stated otherwise:
• LOW: VIN ≤VIL(AC)max; HIGH: VIN ≥VIH(AC)min
• Midlevel: Inputs are VREF = VDD/2.
• RON set to RZQ/0 (34Ωꢀꢁ
.
• RTT,nom set to RZQ/6 (4±Ωꢀꢁ
• RTT(WR) set to RZQ/2 (12±Ωꢀꢁ
• QOFF is enabled in MR1.
• ODT is enabled in MR1 (RTT,nom) and MR2 (RTT(WR)).
• TDQS is disabled in MR1.
• External DQ/DQS/DM load resistor is 25Ω to VDDQ/2.
• Burst lengths are BL8 fixed.
• AL equals ± (except in IDD0).
• IDD specifications are tested after the device is properly initialized.
• Input slew rate is specified by AC parametric test conditions.
• Optional ASR is disabled.
• Read burst type uses nibble sequential (MR±[3] = ±).
• Loop patterns must be executed at least once before current measurements begin.
