Abstract

本申请涉及三维闪存存储器、垂直NAND、数据迁移、粒子群算法技术领域，具体而言，涉及一种NAND闪存数据迁移方法，能适用于3D闪存和垂直NAND闪存存储。包括如下步骤：步骤1：外置计算器获取NAND储存器中最小的物理页的物理地址以及最小的物理块的物理地址，建立仿真地址表格；步骤2：监测NAND储存器中控制器的控制指令，控制指令包括对物理页的读取指令、物理页的写入指令，以及物理块的擦除指令。本申请通过外置计算器强大的处理能力，彻底解决了NAND闪存内置控制器算力严重受限的瓶颈，得以实时运行复杂的粒子群优化算法，对仿真出的NAND物理状态进行全局、动态、多目标协同优化，生成高精度的最佳平衡指令。
