Abstract
According to an example embodiment, a semiconductor memory device may include a memory core, input circuit, and/or an output circuit. The input circuit may be configured to generate second data from first data using latch circuits operating in response to input control signals enabled during different periods. The input circuit may be further configured to provide the second data to the memory core. The second data may have 2N times the number of bits of the first data, where N is a positive integer. The output circuit may be configured to generate fourth data from third data using latch circuits operating in response to output control signals enabled during different periods. The output circuit may be further configured to provide the fourth data to data output pins. The fourth data may have ½N times the number of bits of the third data. A method of inputting/outputting data is also provided.
