DRAM Operating Conditions
Recommended AC operating conditions are given in the DDR4 component data sheets.
Component specifications are available at micron.com. Module speed grades correlate
with component speed grades, as shown below.
Table 12: Module and Component Speed Grades
DDR4 components may exceed the listed module speed grades; module may not be available in all listed speed grades
Module Speed Grade Component Speed Grade
-2G6 -075
-2G4 -083E
-2G3 -083
-2G1 -093E
-1G9 -107E
Design Considerations
Simulations
Micron memory modules are designed to optimize signal integrity through carefully de-
signed terminations, controlled board impedances, routing topologies, trace length
matching, and decoupling. However, good signal integrity starts at the system level. Mi-
cron encourages designers to simulate the signal characteristics of the system's memo-
ry bus to ensure adequate signal integrity of the entire memory system.
Power
Operating voltages are specified at the edge connector of the module, not at the DRAM.
Designers must account for any system voltage drops at anticipated power levels to en-
sure the required supply voltage is maintained.
