Sage Microelectronics Assigned Patent

Sage Microelectronics Corporation, Campbell, CA, has been assigned a patent (11,138,110) developed by Luo, Jianjun, Campbell, CA, Liu, Hailuan, Zhejiang, China, and Tsu, Chris, Campbell, CA, for a “data management for memory devices.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Designs of persistently managing mapping tables are described. To keep the performance of writing data into or reading out data from a storage device, such as flash memory, RAM (Random Access Memory) is often used to manage the mapping tables. To prevent the mapping tables from being damaged for whatever reason (e.g., power failure, MRAM, Magnetic RAM) is employed to keep the mapping tables in magnetic domains while the RAM is only used for updating the content of the mapping tables. Not only is the capacity for RAM is significantly reduced, the mapping tables are securely maintained in MRAM and available to RAM while data is being written into or read out from the storage device.”

The patent application was filed on April 30, 2020 (16/864,070).
