Title: In-Chul Jeong: Innovator in Semiconductor Memory Technology

Introduction

In-Chul Jeong is a prominent inventor based in Suwon-si, South Korea, known for his significant contributions to semiconductor memory technology. With a total of 14 patents to his name, Jeong has made remarkable advancements in the field of dynamic random access memory (DRAM) and memory device control.

Latest Patents

One of Jeong's latest patents is a device and method of controlling refresh operation for dynamic random access memory (DRAM). This innovative method involves storing a first row address corresponding to a first row of a memory cell array and one or more second row addresses. The method sequentially generates row addresses as a refresh row address during a refresh interval. When a generated row address matches one of the second row addresses, the generation of row addresses is halted, and the second row address along with the first row address is outputted as the refresh row address.

Another notable patent is related to a semiconductor memory device controlling refresh cycles. This device includes a memory cell array, a refresh control circuit, an address counter, and an address converter. The refresh control circuit receives a refresh command and outputs multiple refresh control signals during a refresh cycle. The address counter generates counting signals for refreshing memory cells, while the address converter outputs refresh addresses by converting these counting signals in response to a cycle select signal.
