Abstract

A key-value storage architecture with data compression is shown. During the garbage collection, the controller compresses valid pieces of key-value data to generate a piece of compressed data. Each piece of key-value data is in key-value format. The controller codes the piece of compressed data to generate a first piece of compressed key-value data that is also in key-value format, and programs the first piece of compressed key-value data into the non-volatile memory.
