Silicon Motion
Design and Maintain FTL Architecture
Develop and maintain the Flash Translation Layer (FTL) including I/O flow, Garbage Collection, and Wear Leveling algorithms to ensure data integrity and maximize NAND endurance.
Block Management and Metadata Handling
Implement bad block detection, isolation, and data migration mechanisms to manage block lifecycle.
Design robust metadata structures to support fast mapping table reconstruction and system boot.
Error Handling Mechanisms
Prevent and mitigate NAND‑related issues such as read disturb, program/erase failures, and retention loss.
Implement RAID encode/decode flows to guarantee data reliability.
Power‑Loss Protection
Design and implement power‑loss protection algorithms to maintain data consistency and metadata integrity during unexpected shutdowns.
Verify and optimize power‑loss recovery flow to ensure fast and reliable system startup.
Performance and Resource Optimization
Optimize channel/die/plane access scheduling and parallelism to improve throughput and reduce latency.
Enhance DRAM/SRAM usage efficiency and reduce write amplification for better endurance and performance.
Debugging and Validation
Develop and analyze FTL traces and logs for performance profiling and issue root‑cause analysis.
Conduct stress testing, mixed workload testing, power‑fail tests, and corner‑case verification to ensure firmware stability and reliability.
Collaborate with Validation, Hardware, and ASIC teams to resolve cross‑functional issues and ensure system robustness.
