Stresses greater than those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a
stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational
sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reli-
ability.

1. DRAM Component Case Temperature is the surface temperature in the center on the top side of any of the DRAMs. For
measurement conditions, please refer to the JEDEC document JESD51-2.
2. Within the DRAM Component Case Temperature range all DRAM specification will be supported.
3. Above 85oC DRAM case temperature the Auto-Refresh command interval has to be reduced to tREFI = 3.9 µs.
4. Self-Refresh period is hard-coded in the DRAMs and therefore it is imperative that the system ensures the DRAM is below
85oC case temperature before initiating self-refresh operation.

1 Under all conditions, VDDQ must be less than or equal to VDD
2 Peak to peak AC noise on VREF may not exceed ± 2% VREF (DC).VREF is also expected to track noise variations in VDDQ.
3 For any pin on the DIMM connector under test input of 0 V ≤ VIN ≤ VDDQ + 0.3 V.
