Introduction

Hyun-chul Yoon is an inventor based in Yongin, South Korea, whose patent work focuses on semiconductor memory devices and their operation. He is associated with Samsung Electronics Co., Ltd. His portfolio includes 6 patents.

Latest Patents

One of Yoon’s latest patents, “Memory Device Performing Test on Memory Cell Array and Method of Operating the Same,” describes a memory device with a cell array, word-line drivers, and a test manager. The test manager changes the capacitance of a bit line by driving selected word lines, then drives other word lines to test them. This approach supports testing of the memory array’s word lines.

Another recent patent, “Semiconductor Memory Devices, Methods of Operating Semiconductor Memory Devices and Memory Systems,” concerns a memory cell array divided into two regions. An access control circuit uses a command, an address, and fuse information to identify the regions and access them differently. The command and address are supplied by an external device.
