Abstract
A memory device includes: a normal cell region suitable for storing write data and outputting read data; a parity cell region suitable for storing write parity bits and outputting read parity bits; a pattern generation circuit suitable for generating test data whose value is sequentially increased, and providing the test data as the write data, in a first test mode; an error correction circuit suitable for generating the write parity bits based on the write data, correcting an error of the read data based on the read parity bits, and outputting the error-corrected data; and an output circuit suitable for compressing the error-corrected data and outputting the compressed data, wherein the output circuit is further suitable for compressing the read parity bits output from the parity cell region to output the compressed data, in the first test mode.
