Title: Innovations of Ngok Ying Chu
Introduction
Ngok Ying Chu is a notable inventor based in Los Altos, CA. He has made significant contributions to the field of memory systems, holding a total of 5 patents. His work focuses on enhancing memory architecture to improve efficiency and performance.
Latest Patents
One of his latest patents is a memory system with a shared buffer architecture for multiple decoders and a method of operating such a memory system. This innovative design reduces transfer latency and power consumption. The system includes a memory device that generates codewords and a dynamic memory access (DMA) assembly that receives these generated codewords. The first decoding stage features a checksum module and a shared memory buffer, which manages the codewords received from the DMA assembly. The second decoding stage consists of a bit-flipping (BF) decoder and a min-sum (MS) decoder, both communicating with the shared memory buffer. The memory manager plays a crucial role in controlling the assignment and reassignment of codewords among the destination ports.
Another significant patent is the VSS LDPC decoder with improved throughput for hard decoding. This memory system includes a pre-processing checksum unit that computes a checksum of hard read data during the first decoding iteration. The low-density parity-check (LDPC) decoder stores the sign values and utilizes the checksum to decode a codeword in subsequent iterations, enhancing the overall decoding process.
