Abstract
A semiconductor memory device includes a parity generation circuit which generates a parity bit corresponding to a first number of data bits, a memory cell array including memory cells, and having first and second areas, the first area storing data, the second area storing the parity bit, a syndrome generation circuit which generates a syndrome bit for correcting an error in read data which are read from the first area, has the first number of data bits and corresponds to the parity bit read from the second area, based on the parity bit and the read data, and a parity correction circuit which corrects the parity bit generated by the parity generation circuit. The parity generation circuit generates the parity bit for data which includes input data and a part of the read data.
