Storage system in key-value storage architecture with data compression, and NVM control

Shannon Systems Ltd., Shanghai, China, has been assigned a patent (11,402,995) developed by Chen, Chao, and Miao, Ningzhong, Shanghai, China, for data storage system in a key-value storage architecture with data compression, and non-volatile memory control method.

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A key-value storage architecture with data compression is shown. A computing unit is configured to estimate the average compression rate factor of a non-volatile memory. The computing unit is further configured to estimate storage space consumption of the non-volatile memory based on the average compression rate factor, and programming of the non-volatile memory is prohibited if to the storage space consumption exceeds a predefined threshold. The average compression rate factor is dynamically updated, and is a weighted result of compression rate factors of several storage units of the non-volatile memory.

The patent application was filed on February 1, 2021 (17/163,739).
