Latest Patents

Cho’s listed recent patents address memory architecture, data management, and the performance of nonvolatile storage.

“Data Storage Device, Memory System, and Computing System Using Nonvolatile Memory Device” describes a storage device with two or more data storage areas that may use different types of nonvolatile memory cells. In at least one area, memory blocks are selected sequentially, with metadata stored in the currently selected block. Distributing metadata across the device is intended to avoid separate merging and wear-leveling operations, helping improve device lifetime and writing performance.

“Memory System and Block Merge Method” describes a flash memory system with data blocks, log blocks, and free blocks. Its flash translation layer performs merge operations during background periods to maintain at least a reference number of free blocks, converting selected data or log blocks into free blocks. It can also convert free blocks into data and log blocks as needed.

Career Highlights

Cho’s listed inventions concern the organization and management of nonvolatile memory. The described approaches address block selection, metadata distribution, and background merging to support storage performance and memory-block management.
