He holds a total of 3 patents that focus on improving the reliability of non-volatile storage devices. His work has been instrumental in enhancing data management and recovery processes.

Latest Patents

One of Kuo's latest patents is titled "Method and system for improving open block data reliability." This invention involves systems, methods, and devices designed to manage open blocks within non-volatile storage devices. The goal is to enhance the reliability of these devices. When a shut-down request is received from a host device, the storage device fetches information about open blocks and their boundary regions that are susceptible to data reliability issues. For each identified boundary region, the device programs a region contiguous to it. Additionally, the device updates an XOR parity table used for XOR parity management with the information that the contiguous region has been programmed. This information can later be used for data recovery in the event of data loss, thereby improving the overall reliability of the non-volatile storage device.

Another significant patent by Kuo is "Erasure correcting coding using temporary erasure data." In this invention, a data storage device includes a non-volatile memory and a controller. The controller features an erasure correcting code engine that generates first erasure recovery data and temporary erasure recovery data in volatile memory based on data to be written to the non-volatile memory. The first erasure recovery data enables a first type of data recovery, while the temporary data allows for a second type. After verifying that the first data is stored in the non-volatile memory, the controller can discard or modify the temporary erasure recovery data.
