Notes:
1. Operating Temperature is the case surface temperature on the center/top side of the DRAM.
2. Supporting 0 ~ 85°C with full JEDEC AC and DC specifications.
3. Supporting 0 ~ 85°C and being able to extend to 95°C with doubling Auto Refresh commands in frequency to a 32 mS period
4. During operation, the DRAM case temperature must be maintained between -40 to 95°C for Industrial parts under all
