Abstract: A method of managing a memory that can quickly secure an available space is provided. The method includes recording compression ratios of data stored in pages of a main memory, and securing space of the main memory when the main memory has insufficient available space, by compressing data of pages having a compression ratio of a standard value or greater among pages of the main memory and storing the compressed data in the main memory.

Abstract: Provided is an apparatus and method for storing data in a terminal are provided. The apparatus includes a processor for sending a first command to a memory to instruct storage of data in a Single-Level Cell (SLC) area of the memory if a function requiring high-speed storage of large amounts of data is selected; and the memory for storing received data in the SLC area regardless of a size of the data, upon receiving the first command from the processor.
