Title: Kwangmin Han: Innovator in Memory Controller Technology

Introduction

Kwangmin Han is a notable inventor based in Suwon-si, South Korea. He has made significant contributions to the field of memory controller technology, holding two patents that enhance the efficiency and reliability of memory systems. His work is particularly relevant in the context of modern data processing systems.

Latest Patents

Kwangmin Han's latest patents include a memory controller for managing journal data and an operating method of the memory controller. The first patent describes a storage device that features a journal buffer designed to store multiple pieces of journal data. This journal buffer consists of several bank pools and a journal data region. Each piece of journal data includes a first data item linked to a bank address and a second data item associated with a row address. The memory controller is responsible for controlling the journal buffer to temporarily store first pieces of journal data that share the same first data items across at least one of the bank pools. It also rearranges these first pieces based on comparisons of their corresponding second data items.

The second patent focuses on methods for real-time repairing of memory failures that may occur during operations. This operating method involves a memory device that includes both a memory region and a repair memory region. The method entails receiving an address linked to the memory region during a read command, decoding the data retrieved from that address, and detecting any errors present. It generates error type information to indicate the nature of the error and updates a count value associated with the address. This count value reflects how many times the specific error type has occurred. When this count reaches a predetermined threshold, the data stored at that address is backed up to the repair memory region.
