EpoStar Electronics Assigned Three Patents

Memory management and storage controller
Shenzhen EpoStar Electronics Limited Co., Shenzhen, China, has been assigned a patent (10,817,416) developed by Hsiao, Yu-Hua, Hsieh, Hung-Chih, Hsinchu County, Taiwan, and Fang, Tzu-Wei, Taipei, Taiwan, for “memory management method and storage controller.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”A Memory management method for a storage device having a rewritable non-volatile memory module is provided. The rewritable non-volatile memory module has a plurality of physical blocks divided into a plurality of block stripes. The method includes: scanning the physical blocks to identify one or more bad physical blocks among the physical blocks, calculating a plurality of effective weight values corresponding to the block stripes according to a plurality of data accessing time parameters of the rewritable non-volatile memory module, a plurality of valid data counts, and the identified one or more bad physical blocks, and selecting a target block stripe from the block stripes according to the effective weight values to perform a garbage collection operation.”

The patent application was filed on July 17, 2018 (16/036,955).

Memory management and storage controller
Shenzhen EpoStar Electronics Limited Co., Shenzhen, China, has been assigned a patent (10,803,973) developed by Hsiao, Yu-Hua, Hsinchu County, Taiwan, and Chang, Chia-Wei, Kaohsiung, Taiwan, for “memory management method and storage controller.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”A memory management method and a storage controller using the same are provided. The method includes reading a target word-line to identify a plurality of raw Gray code indexes corresponding to a plurality of memory cells of the target word-line, performing a decoding operation on raw data of the target word-line to identify a plurality of decoded Gray code indexes corresponding to the memory cells, calculating a plurality of Gray code absolute bias values corresponding to the memory cells according to the raw Gray code indexes and the decoded Gray code indexes, and identifying one or more abnormal memory cells among the memory cells according to the Gray code absolute bias values, and recording the one or more abnormal memory cells into an abnormal memory cell table, wherein a Gray code absolute bias value of each of the one or more abnormal memory cells is greater than a bias threshold.”

The patent application was filed on November 11, 2019 (16/679,295).

Command processing and storage controller
Shenzhen EpoStar Electronics Limited Co., Shenzhen, China, has been assigned a patent (10,782,919) developed by Chan, Ke-Wei, Hsinchu, Taiwan, Ngu, Di-Hsien, and Hsieh, Hung-Chih, Hsinchu County, Taiwan, for “command processing method and storage controller using the same.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”A command processing method and a storage controller are provided. The command processing method includes performing a command merging process on commands sequentially received by a command queue. The command merging process includes an initialization step and multiple iterations. The initialization step includes transmitting the commands from the command queue to a continuity checking pool, (CCP), transmitting an initial command of the commands from the CCP to a continuity list (CL) and setting a range of the CL. Each of the iterations includes transmitting the commands from the command queue to the CCP, determining whether the commands in the CCP and the range of the CL conform to a continuity condition, and when the commands in the CCP and the range conform to the continuity condition, appending the first command to the CL and resetting the range of the CL according to the first command.”

The patent application was filed on November 8, 2018 (16/184,928).
