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 reliability. 2. Storage Temperature is the case surface temperature on the center/top side of the DRAM. For the measurement conditions, please refer to JESD51-2 standard. 3. VDD and VDDQ must be within 300 mV of each other at all times; and VREFCA must be not greater than 0.6 x VDDQ, When VDD and VDDQ are less than 500 mV; VREF may be equal to or less than 300 mV 4. VPP must be equal or greater than VDD/VDDQ at all times ©Apacer Technology Inc. 9 DRAM Component Operating Temperature Range Symbol Parameter Rating Units Notes Normal Operating Temperature Range 0 to 85 ℃ 1,2 Extended Temperature Range 85 to 95 ℃ 1,3 TOPER Notes: 1. Operating Temperature TOPER is the case surface temperature on the center / top side of the DRAM. For measurement conditions please refer to the JEDEC document JESD51-2. 2. The Normal Temperature Range specifies the temperatures where all DRAM specifications will be supported. During operation, the DRAM case temperature must be maintained between 0℃ - 85℃ under all operating conditions. 3. Some applications require operation of the DRAM in the Extended Temperature Range between 85℃ and 95℃ case temperature. Full specifications are guaranteed in this range, but the following additional conditions apply: a. Refresh commands must be doubled in frequency, therefore reducing the Refresh interval tREFI to 3.9 µs. It is also possible to specify a component with 1X refresh (tREFI to 7.8µs) in the Extended Temperature Range. Please refer to the DIMM SPD for option availability b. If Self-Refresh operation is required in the Extended Temperature Range, then it is mandatory to either use the Manual Self-Refresh mode with Extended Temperature Range capability (MR2 A6 = 0b and MR2 A7 = 1b), in this case IDD6 current can be increased around 10~20% than normal Temperature range. ©Apacer Technology Inc. 10 Operating Conditions Recommended DC Operating Conditions – DDR4 (1.2V) operation Rating Symbol VDD Parameter Supply Voltage VDDQ Supply Voltage for Output VPP Activation Supply Voltage Units Notes 1.26 V 1,2,3 1.2 1.26 V 1,2,3 2.5 2.75 V 3 Min.
