Memory Controller L2P Mapping Updates with Adaptive Timing

The patent applies dynamics by making the update trigger condition adaptive rather than fixed. The controller dynamically adjusts the trigger threshold based on the detected write mode (sequential or random), allowing the system to optimize L2P table update timing for different workload characteristics. This resolves the contradiction by enabling high adaptability through dynamic parameter adjustment while maintaining relatively simple implementation through mode detection and conditional logic.

The patent changes the parameter of update trigger threshold based on write mode. When sequential write is detected, a first threshold is used; when random write is detected, a second threshold is used. This parameter change allows the system to adapt to different write patterns, improving versatility while keeping the mechanism simple through straightforward parameter switching based on mode identification.

The patent applies partial action by updating the L2P table selectively rather than continuously. The update operation is triggered only when specific conditions are met (based on write mode and threshold comparisons), avoiding unnecessary updates. This reduces update time and latency while maintaining reliability by ensuring updates occur at appropriate moments when data accuracy requirements are met.

The patent implements periodic-like action through threshold-based triggering. Instead of continuous updating, the system monitors write operations and triggers updates periodically when accumulated changes reach the dynamically determined threshold. This approach balances reliability (ensuring updates occur when needed) with time efficiency (avoiding excessive frequent updates).
