Latest Patents

One of Lee’s latest patents, “Memory Device with Soft Programmed Dummy Cells and Method of Operating the Same,” describes a memory block containing strings of memory cells separated by dummy cells. The device’s peripheral circuit performs normal programming on memory cells and soft programming on dummy cells. The disclosed method targets the fourth dummy cell, farthest from the area receiving precharge voltage, for soft programming while normal programming is performed on other memory cells. This arrangement addresses programming behavior within the memory block.

Another patent, “Controller, Storage Device and Method for Operation to Balance Memory Degradation,” concerns reducing differences in degradation across areas of volatile memory that stores data associated with non-volatile memory. At a preset time, the system can change the area assigned to that data according to its type, helping balance memory wear.

Career Highlights

Lee’s disclosed inventions address both memory-cell programming and the management of data in storage devices. These areas are relevant to the reliability and operation of memory systems.
