Latest Patents

Seok Lee's latest patents include innovative solutions aimed at mitigating issues related to 3D NAND storage devices. The first patent, titled "Mitigating Edge Layer Effect in Partially Written Blocks," describes a storage device that evaluates whether a block is partially written upon receiving a shutdown command. If a block is found to be partially written, dummy lines are written after the last written wordline of the block. This approach addresses blocks with a fill percentage below a certain threshold, which is determined by the PEC count of the block. Additionally, if the maximum retention time is exceeded for data in a partially written block, dummy lines are also written to ensure data integrity.

The second patent, "Adaptive Read Disturb Algorithm for NAND Storage Accounting for Layer-Based Effect," outlines a method for performing test reads on 3D NAND storage. This method involves reading only the least significant bit (LSB) pages and utilizing a repeating pattern of reading two layers while skipping two. The frequency of test reads is adjusted based on errors detected during the process, with counter thresholds updated accordingly. This adaptive approach enhances the reliability of data storage by specifying error thresholds that trigger garbage collection.
