Stresses greater than those listed 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
outside those indicated in the device data sheet is not implied. Exposure to absolute
maximum rating conditions for extended periods may adversely affect reliability.

It is imperative that the DDR3 SDRAM device’s temperature specifications, shown in
Table 5 on page 10, be maintained to ensure the junction temperature is in the proper
operating range to meet data sheet specifications. An important step in maintaining the
proper junction temperature is using the device’s thermal impedances correctly. Ther-
mal impedances listed in Table 6 on page 10 apply to the current die revision and pack-
ages.
Incorrectly using thermal impedances can produce significant errors. Read Micron tech-
nical note
Table 6. For designs that are expected to last several years and require the flexibility to
use several DRAM die shrinks, consider using final target theta values (rather than exist-
ing values) to account for increased thermal impedances from the reduction in die size.
The DDR3 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 to satisfy the case
temperature specifications.
