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 specifications will be supported
3) Above 85 °C DRAM Case Temperature the Auto-Refresh command interval has to be reduced to

temperature range, the High Temperature Self Refresh has to be enabled by
setting EMR(2) bit A7 to “1”. When the High Temperature Self Refresh is enabled there is an increase of
