Stresses greater than those listed in Table 9 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
Micron encourages designers to simulate the performance of the module to achieve
optimum values. Simulations are significantly more accurate and realistic than a gross
estimation of module capacitance when inductance and delay parameters associated
with trace lengths are used in simulations. JEDEC modules are currently designed using
simulations to close timing budgets.
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 10.
