Introduction

Hyunsub Kim is an inventor based in Suwon-si, South Korea, whose patent work focuses on storage devices, memory controllers, and data-management methods. He is associated with Samsung Electronics Ltd. and has 2 patents listed in the provided information.

Latest Patents

Kim’s listed patents address storage architecture and the management of metadata in nonvolatile memory.

“Storage Device Supporting Virtual Groups and Operating Method of Storage Device” describes a storage device with nonvolatile memory and a controller that handles host data input/output requests. The controller generates a physical address using selected bits from a logical address and a second physical address recorded in a mapping table, which stores correlations between logical and physical addresses.

“Memory Controller, Storage Device Including Memory Controller, and Operating Method of Memory Controller” concerns a storage device with nonvolatile memory, buffer memory, and a memory controller. The buffer stores metadata blocks and journal data containing updates to that metadata. The controller estimates recovery time from journal-entry timestamps and uses that estimate to guide writing metadata and journal data to nonvolatile memory.
