SK hynix and its U.S. subsidiary Solidigm (SK hynix NAND Product Solutions Corp.) have jointly filed a Korean patent application — their first co-owned filing in Korea, reflecting the continued integration of technology development following SK hynix's acquisition of Intel's NAND business.
The application, titled "Memory Device for Repairing Input Data During Program Suspend Operation and Memory System Including the Same and Operation Method of the Same" (KR10-2024-0147807), was filed in October 2024 and published in May 2025.
The filing claims priority to two U.S. applications: U.S. Provisional Application No. 63/596,875 filed in November 2023, and U.S. Application No. 18/824,841 filed in September 2024.
The invention covers a memory-controller architecture designed to maintain and recover data integrity in NAND flash — particularly 3D NAND — during program-suspend events. By combining latch data and partially programmed cell states with controller-side logical operations that vary by suspend timing, the technology supports robust recovery of input data. Its target applications include 3D NAND products such as TLC and QLC devices, SSD controllers, multi-plane and multi-channel programming environments, and systems prone to power interruptions or abrupt suspensions.
As of Dec. 5, 2025, Solidigm has a total of 28 published patent applications in Korea, according to KIPRIS. The figure includes one application jointly filed with its parent company, SK hynix. The joint filing marks the first co-owned Korean patent between the two entities and reflects the continued integration of technology development following SK hynix’s acquisition of Intel's NAND business.
