SEMICONDUCTOR MEMORY DEVICE, CONTROLLER, AND MEMORY SYSTEM

摘要

A semiconductor memory device includes a memory cell array that is capable of storing data in a nonvolatile manner, and a control section that controls data access to the memory cell array. The memory cell array stores the same data redundantly in a plurality of pages. The control section executes a reading operation on the plurality of pages that store the same data redundantly to read the data. The data that is stored redundantly may be management data or user data.
