Abstract: The semiconductor memory device includes first group dies including at least one buffer die, and second group dies including a plurality of memory dies stacked on the first group dies and conveying data through a plurality of TSV lines. Here, at least one of the plurality of memory dies includes a first type ECC circuit which generates transmission parity bits using transmission data to be transmitted to the first group die, and the buffer die includes a second type ECC circuit which corrects, when a transmission error occurs in the transmission data received through the plurality of TSV lines, the transmission error using the transmission parity bits and generates error-corrected data.
