Stresses greater than those listed in Table 7 may cause permanent damage to the
module. This is a stress rating only, and functional operation of the module at these or
any other conditions outside those indicated on the device data sheet is not implied.
Exposure to absolute maximum rating conditions for extended periods may adversely
affect reliability.
1. For further information, refer to technical note
Recommended AC operating conditions are given in the DDR 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.

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 the system’s
memory bus to ensure adequate signal integrity of the entire memory system.
Operating voltages are specified at the DRAM, not at the edge connector of the module.
Designers must account for any system voltage drops at anticipated power levels to
ensure the required supply voltage is maintained.
