Abstract:
According to example embodiments, a semiconductor memory device includes a memory cell array, a multi-purpose register, a data output circuit, and a mode register. The memory cell array is configured to store data. The multi-purpose register is configured to store a data pattern. The data output circuit is configured to output the stored data during a first output mode and output the stored data pattern during a second output mode. The mode register is configured to set the first or second output mode according to a logic level of a portion of a content of the mode register.
