1) DRAM Component Case Temperature is the surface temperature in the center on the top side of any of the DRAMs.
2) Within the DRAM Component Case Temperature range all DRAM specification will be supported.
3) Above 85 °C DRAM case temperature the Auto-Refresh command interval has to be reduced to t_REFI = 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 85 °C case
temperature before initiating self-refresh operation.
5) Up to 3000 m
