Title: HyunJu Yoon and Nonvolatile Memory Innovations

Introduction

HyunJu Yoon is an inventor based in Gyeonggi-do, South Korea, whose patent work focuses on nonvolatile memory systems and protecting data during power interruptions. She is associated with SK hynix Inc. Her portfolio includes 4 patents.

Latest Patents

Yoon’s recent patent work addresses memory modules that combine volatile and nonvolatile memory, with mechanisms for backing up data when host power fails.

“Nonvolatile Dual In-Line Memory Module and Method for Operating the Same” describes a module with volatile memory devices, at least one nonvolatile memory device, and a controller that backs up volatile-memory data after a power failure or a backup instruction. The controller assigns different command address latency values to the volatile memory devices as part of the backup operation.

“Power-Down Interrupt of Nonvolatile Dual In-Line Memory System” concerns managing backup and restoration in response to host power failure and recovery. Its controller can interrupt a backup when power returns, check whether enough erased blocks are available in nonvolatile memory, erase a new block if needed, and back up data associated with that block when a power failure or host instruction calls for it.

Career Highlights

Yoon’s listed inventions demonstrate a focus on data preservation in memory systems. The described designs address both the coordination of volatile and nonvolatile memory and the handling of backup operations as power conditions change.

Collaborations

Hyunsu Yoon and Jeongsu Jeong are identified as Yoon’s coworkers. The available information does not specify their roles in the patents or the nature of their collaboration.

Conclusion

HyunJu Yoon’s patent work at SK hynix Inc. centers on reliable data backup and power-aware operation in nonvolatile memory modules.
