Title: Innovations of Jinghuan Chen in Data Storage Technology
Introduction
Jinghuan Chen is a notable inventor based in Irvine, CA, who has made significant contributions to the field of data storage technology. With a total of 4 patents to his name, Chen's work focuses on enhancing the reliability and efficiency of storage devices.
Latest Patents
One of his latest patents is a "Data retention (DR) warning system." This invention involves aspects of a storage device that includes a memory and a controller. The controller is designed to determine when to perform garbage collection on a superblock. During this process, the superblock is typically moved into an erase pool for erasure. However, Chen's method measures the raw bit error rate (RBER) of the superblock prior to erasure. This measured RBER can be used to estimate the data retention time of the storage device, providing customers with an early warning notification if a health metric reaches a threshold retention time.
Another significant patent is related to a "Disk drive generating quality metric map for a data track while in different configurations." This invention describes a disk drive that comprises a disk with multiple servo tracks defined by servo sectors, a head actuated over the disk, and control circuitry that includes a read channel. The read channel is configured to read segments of data tracks and generate quality metrics at periodic points along these segments, enhancing the overall performance of the disk drive.
