Title: Innovations by Inventor Stanley M. Chang

Introduction

Stanley M. Chang, based in Irvine, California, is an accomplished inventor with two notable patents to his name. His work primarily focuses on enhancing data integrity and error correction methods within disk drive systems. Chang's innovative contributions have significant implications for data reliability and storage technology.

Latest Patents

Chang's latest patents include advanced methodologies for ensuring data integrity and error correction in data storage systems. The first patent introduces a data integrity code that combines logical block address (LBA) information with circuit implementation. This code enables verification of data block LBA during both transfer and retrieval processes. By embedding LBA information within the data integrity code, it serves as a cross-check mechanism to detect miscorrections by error correction codes (ECC). Such features are particularly vital in ensuring that data blocks maintain consistent values between the host interface, buffer memory, and data sequencer.

The second patent focuses on reconstructing syndromes for bi-level on-the-fly error correction in disk drive systems. In this approach, a dedicated error correction hardware attempts to rectify data errors using a syndrome generated from data and ECC bits. When the hardware is unable to resolve the errors, the original syndrome value is reconstructed through repetitive processing, allowing the system to manage persistent errors effectively under firmware control.
