Latest Patents

Cheng-Yu Tsai's latest patents include a method and non-transitory computer-readable storage medium and apparatus for configuring a current block to program data. This invention introduces a method for configuring a current block to program data, performed by a processing unit. The process involves dividing the storage space of a flash module into a static area and a dynamic area. It also includes entering a first mode to obtain a first empty storage block (SB) from the dynamic area and erasing it to configure it as a non-SLC block. Additionally, it describes entering a second mode to obtain a second empty SB from the static area and erasing it to configure it as an SLC block, based on specific conditions related to background garbage collection.

Another notable patent is a method and non-transitory computer-readable storage medium and apparatus for garbage collection with determined host-address to flash-address mapping (H2F) sub-tables in a flash memory device. This invention outlines a method for garbage collection in a flash memory device, which includes finding a source block associated with a hit accumulated valid page count that exceeds the total number of physical pages in a destination block. The method further details the labeling of source blocks, obtaining H2F sub-tables, and reprogramming user data based on valid pages.
