Electrical & Timing Specifications
Mechanical Specifications
Environmental Specifications & Compliance
Operating temperature is specified as DRAM case temperature (TC).
Compatibility & Qualification
Check the DIMM socket, memory controller, board layout and firmware when selecting a module. Compatibility is verified on the target configuration according to the project requirements.
Industrial Program Controls
Production Verification
Production-level verification
- Incoming, in-process, final and outgoing quality control
- SPD programming and verification
- Module functional verification before shipment
Project-level qualification
- Target-platform compatibility verification
- Stability verification under the defined operating conditions
- Application-specific qualification where the program requires it
Production-level verification is part of the manufacturing flow. Project-level qualification is scoped per program.
