Semiconductor memory device

摘要

A semiconductor memory device includes a memory unit configured in page units, an error correction code (ECC) module for generating error correcting codes, a page information addition module for generating page information, and a controller for controlling the reading and writing of data to the memory unit. The controller is configured to associate error correction code information and page information with each frame unit of data written to the memory unit and to store the associated information with each frame unit. The controller is configured to output data to an external host in sizes less than one page unit, such as one frame unit.

1. A semiconductor memory device, comprising:
a memory unit configured for reads and writes in page units; an error correction code module configured to generate an error correcting code for each frame unit within a page unit; a page information addition module configured to add page information to each frame unit; and a controller configured to control a writing of data to the memory unit in response to a write request from an external host, such that for each frame unit of data that is written, the error correcting code and the page information associated with the frame unit of data are written alongside therewith, and configured to control a reading of data that has a size less than a page unit from the memory unit in response to a read request from the external host.
