Layered Iterative Error Correction With Parity-Based Early Stopping

The patent applies partial action by implementing early stopping criteria in layered iterative error correction. Instead of always completing all layers and iterations, the decoder stops when a codeword satisfies stopping criteria (such as minimum Hamming weight or parity check satisfaction). This partial execution reduces power consumption while maintaining sufficient error correction capability for most codewords, resolving the contradiction between reliable error correction and power consumption in portable devices.

The patent implements partial action through early stopping criteria that prevent completion of all iterative layers when errors are already corrected. By monitoring codeword properties during iteration and stopping when stopping criteria are met, the system achieves effective error correction with reduced processing time, resolving the contradiction between error correction capability and latency constraints in memory systems.

The patent applies self-service by enabling the error correction system to automatically monitor its own state and make stopping decisions based on predefined criteria. The decoder independently evaluates codeword properties (such as Hamming weight or parity check results) during iteration and autonomously determines when to stop, eliminating the need for complex external control logic. This resolves the contradiction between error correction capability and device complexity.
