Abstract
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.
