Stresses greater than those listed Table 12 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 specification is not
implied. Exposure to absolute maximum rating conditions for extended periods may
affect reliability.
It is imperative that the SDRAM device’s temperature specifications, shown in Table 13
on page 42, be maintained in order 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. The
thermal impedances are listed in Table 14 on page 42 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 14. 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 in order to satisfy the case
temperature specifications.
