Notes:
It is imperative that the SDRAM device’s temperature specifications, shown in Table 5
(page 18), be maintained to ensure the junction temperature is in the proper operat-
ing range to meet data sheet specifications. An important step in maintaining the
proper junction temperature is using the device’s thermal impedances correctly. The
thermal impedances are listed in Table 6 (page 19) for the applicable die revision and
packages being made available. These thermal impedance values vary according to the
density, package, and particular design used for each device.
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 6 (page 19). To ensure the compatibility of current and future designs,
contact Micron Applications Engineering to confirm thermal impedance values.
The SDRAM device’s safe junction temperature range can be maintained when the T
specification is not exceeded. In applications where the device’s ambient temperature
is too high, use of forced air and/or heat sinks may be required to satisfy the case tem-
perature specifications.

fined by the JEDEC EIA/JESD51 standards. Take care to ensure that the thermocouple
bead is touching the case.
