Abstract
A semiconductor memory device that can easily recognize the content of errors in data is provided. The semiconductor memory device includes a memory cell array, an error detection and correction circuit, and an input/output circuit. The memory cell array includes a plurality of memory cells. The error detection and correction circuit detects and corrects error bits included in the data output by the memory cell array. The error detection and correction circuit activates an error detection signal when the data includes a correctable error bit. The input/output circuit stops the clocking of the data strobe signal output with data when the data includes uncorrectable error bits.
