Abstract
A semiconductor memory device suppressing a shift between data output from a plurality of memory chips and a DQS signal. A flash memory device of the disclosure includes memory chips, a plurality of IO terminals capable of inputting and outputting data, and a DQS terminal. Each of the memory chips includes an output circuit used to output data and a DQS output circuit. The DQS output circuit is used to output the DQS signal for defining a timing of the data output from the output circuit. The DQS signal output from each of the DQS output circuits of the memory chips is supplied to the DQS terminal.
