DATA INTEGRITY PROTECTION FOR RELOCATING DATA IN A MEMORY SYSTEM

Methods, apparatuses, and systems related to data management and security in a memory device are described. Data may be stored in a memory system, and as part of an operation to move data from one region to another in the memory system, the data may be validated using one or more hash functions. For example, a memory device may compute a hash value of some stored data, and use the hash value to validate another version of that stored data in the process of writing the other version stored data to a region of the memory system. The memory device may store another hash that is generated from the hash of the stored data and a record of transactions such that transactions are identifiable; the sequence of transactions within the memory system may also be identifiable. Hashes of transactions may be stored throughout the memory system or among memory systems. 描述了与存储器装置中的数据管理和安全性相关的方法、设备和系统。数据可存储于存储器系统中，且作为将数据从所述存储器系统中的一个区域移动到另一区域的操作的部分，可使用一或多个散列函数验证所述数据。举例来说，存储器装置可计算一些存储数据的散列值，并在将另一版本的所述存储数据写入到所述存储器系统的区域的过程中使用所述散列值
