Abstract
Disclosed are a semiconductor memory device, and a method of driving the same, and a cyclic redundancy check code generating circuit capable of performing cyclic redundancy check. A semiconductor memory device according to an aspect of the present invention includes a memory cell array, a data processing unit receiving data that is read from the memory cell array and selectively outputting at least some of the data according to ordering information, bit structure information, and burst length information, and a check code generating unit generating a cyclic redundancy check code to detect an error in the data being output, the check code generating unit generating and outputting the cyclic redundancy check code by using the read data, the ordering information, the bit structure information, and the burst length information.
