Problems solved by technology

[0009] If NVRAM is used as the main memory instead of DRAM, it is problematic since higher application layer software of the operating system (OS) and computer systems (such as existing portable terminals) does not consider wear leveling

Abstract

A device and method for converting memory addresses and data in a terminal. The device includes: a random key generator configured to generate a new random key each time the terminal is turned on; an address mapper configured to use the random key to convert an address for data writing or data reading The address of the storage area, and send the converted address to the data converter; the data converter is configured to use the converted address to convert the data to be written to the memory, and use the converted address to convert the data to be read from the memory Convert the acquired data to raw data.

Description

technical field [0001] The present disclosure relates to an apparatus and method for converting addresses and data of a memory in a terminal. More particularly, the present disclosure relates to an apparatus and method for converting addresses and data of a memory in a terminal in such a manner that an entire area of ​​the memory can be uniformly worn and data can be protected. Background technique [0002] Volatile memory, such as dynamic random access memory (DRAM) and static random access memory (SRAM), is commonly used as main memory and cache memory. In view of the advantages of random access and fast operation of volatile memory, volatile memory is suitable for storing codes and data to be processed in a central processing unit (CPU). However, if power is not supplied to the volatile memory, the stored data is erased from the volatile memory, which makes the volatile memory unusable independently for long-term data storage. Therefore, a nonvolatile memory such as a h...
