Stresses greater than those listed in absolute maximum rating table 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 specication is not implied. Exposure to absolute maximum rating conditions for extended periods
may adversely affect reliability.
NOTES:
1. TCASE is specied at 95°C only when using 2X refresh timing (tREFI = 7.8μs at or below 85°C; tREFI = 3.9μs above 85°C);.DDR2 SDRAM component datasheet, though the
FBDIMM does not have an IT option.
2. See applicable DDR2 SDRAM component datasheet for tREFI and extended mode register setting. The tREFIIT parameter is used to specify the doubled refresh interval
neceassary to sustain 95°C operation; however, the FBDIMM does not have an IT option.
