Stresses greater than those listed in Table 9 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 each device’s data sheet, is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect reliability.
1. Refresh rate is required to double when T
2. For further information, refer to technical note TN-00-08: Thermal Applications, available
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 DDR2 component data sheets.
Component specifications are available on Micron’s Web site at www.micron.com.
Module speed grades correlate with component speed grades, as shown in Table 10.
