Title: The Innovations of Hyunseung Han

Introduction

Hyunseung Han is a prominent inventor based in Seoul, South Korea. He has made significant contributions to the field of technology, particularly in the areas of data storage and error correction. With a total of six patents to his name, Han's work has had a considerable impact on the industry.

Latest Patents

One of his latest patents is the "Low Density Parity Check Decoder and Storage Device." This invention involves a low density parity check (LDPC) decoder that initializes variable nodes with a value of a codeword. It outputs the updated variable nodes as decoded messages with reference to an irregular parity check matrix. The LDPC decoder includes multiple unit logic circuits that can operate in either a single mode or a multi-mode. In single mode, all unit logic circuits update one variable node group, while in multi-mode, they update several variable node groups in parallel. A mode controller manages the updating process based on the degree of the variable nodes.

Another significant patent is the "Storage Device and Operating Method of Storage Device." This invention features a nonvolatile memory device and a memory controller. The memory controller receives first data from the nonvolatile memory device based on a first read command and performs error correction. If the error correction fails, the controller transmits additional read commands and voltage information to retrieve second and third data. It then adjusts an offset based on this data and performs a soft decision process to enhance data integrity.
