Latest Patents
Li-Jen Lee's latest patents include a method and system for managing a flash memory mass storage system. This application discloses methods to provide defect management, wear leveling, and data security to a mass storage system implemented using flash memory. The flash memory is organized into a plurality of blocks, each with a special region for storing its attributes. In defect management, defects arising from manufacturing and on-the-fly defects are scanned, and defective blocks are marked by altering their attributes. Additionally, the application describes a wear leveling method that ensures the difference between the number of erasures of any two blocks (except defective ones) remains within a predetermined value. Furthermore, a new error detection and correction method is introduced, where the same data is stored in two separate memory locations, allowing for recovery of the correct data through logical operations.
Another significant patent involves an architecture for a mass storage system using flash memory. This architecture organizes the flash memory into multiple blocks divided into several categories. One category is designated for working data, while another serves as a temporary buffer for data intended for writing. The system allows for efficient recycling of blocks, ensuring a constant supply of blocks in the temporary category.
