Latest Patents

Among Yen's latest innovations is a memory system featuring a shared buffer architecture designed for multiple decoders. This state-of-the-art memory system minimizes transfer latency while optimizing power usage. The system comprises a memory device that generates codewords and a dynamic memory access (DMA) assembly responsible for receiving these generated codewords.

The first decoding stage includes a checksum module and a shared memory buffer that efficiently stores and manages codewords. This buffer is overseen by a memory manager that controls the assignment and reassignment of codewords to various destination ports in the system. In the second decoding stage, a bit-flipping (BF) decoder and a min-sum (MS) decoder collaborate with the shared memory buffer via their respective destination ports.

Additionally, another notable patent addresses data dependency mitigation in parallel decoders for flash storage. This innovation enables the memory device to perform parallel decoding of codewords, managing data blocks and their associated error information effectively. The decoding apparatus is designed to identify errors across shared data blocks, allowing for efficient updates and error correction.
