Latest Patents

One of Kwangyoung Lee's latest patents is titled "Back-to-back power loss protection." This invention focuses on increasing the lifetime of data storage devices by implementing a system that detects synthetic power loss protection (PLP) tests. The patent outlines a method where both upper and lower PLP time thresholds are established. When the PLP time exceeds the upper threshold, the device enters a defensive PLP idle state. Conversely, if the PLP time falls between the upper and lower thresholds, the device is in a defensive PLP detecting state. If the PLP time drops below the lower threshold, the device may enter a defensive PLP state based on specific conditions. This innovation prevents unnecessary input/output commands from a host device, thereby conserving resources.

Another notable patent by Kwangyoung Lee is "Optimized read-modify-writes during relocation of overlapping logical blocks." This patent describes systems and methods for executing read-modify-write operations during the relocation of overlapping logical blocks. The method involves receiving a host write command and translating the logical block address to a physical address on the device memory. If the physical address does not align correctly, the method processes a read-modify-write operation for the relevant indirection units during the relocation.
