Stresses greater than those listed may cause permanent damage to the module. This is a
stress rating only, and functional operation of the module at these or any other condi-
tions above 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.
Micron memory modules are designed to optimize signal integrity through carefully
designed terminations, controlled board impedances, routing topologies, trace length
matching, and decoupling. However, good signal integrity starts at the system level.
Micron encourages designers to simulate the signal characteristics of their systems’
memory bus to ensure adequate signal integrity of the entire memory system.
Recommended AC operating conditions are given in the SDRAM component data
sheets. Component specifications are available on Micron’s Web site. Module speed
grades correlate with component speed grades, as shown in Table 8.
