Stresses greater than those listed in Table 5 may cause permanent damage to the de-
vice. This is a stress rating only, and functional operation of the device at these or any
other conditions outside those indicated in the operational sections of this specification
is not implied. Exposure to absolute maximum rating conditions for extended periods
may adversely affect reliability.
It is imperative that the DDR2 SDRAM device’s temperature specifications, shown in
Table 6 (page 21), be maintained in order to ensure the junction temperature is in the
proper operating range to meet data sheet specifications. An important step in maintain-
ing the proper junction temperature is using the device’s thermal impedances correct-
ly. The thermal impedances are listed in Table 7 (page 22) for the applicable and
available die revision and packages.
Incorrectly using thermal impedances can produce significant errors. Read Micron tech-
nical note TN-00-08, “Thermal Applications,” prior to using the thermal impedances
listed in Table 7. For designs that are expected to last several years and require the flexi-
bility to use several DRAM die shrinks, consider using final target theta values (rather
than existing values) to account for increased thermal impedances from the die size re-
duction.
The DDR2 SDRAM device’s safe junction temperature range can be maintained when
the T
ature is too high, use of forced air and/or heat sinks may be required in order to satisfy
the case temperature specifications.
