Notes:
1. Maximum operating case temperature; T
C
is measured in the center of the package.
2. A thermal solution must be designed to ensure the DRAM device does not exceed the
maximum T
C
during operation.
3. Device functionality is not guaranteed if the DRAM device exceeds the maximum T
C
dur-
ing operation.
4. If T
C
exceeds 85°C, the DRAM must be refreshed externally at 2X refresh, which is a 3.9µs
interval refresh rate.
5. The refresh rate must double when 85°C < T
OPER
≤ 95°C.
6. Storage temperature is defined as the temperature of the top/center of the DRAM and
does not reflect the storage temperatures of shipping trays.
