Abstract
A memory device includes a memory cell array, a peripheral circuit, a test mode register set, and a test circuit. The peripheral circuit stores data in the memory cell array or reads data from the memory cell array. The test mode register set stores a delay value. In response to detecting a clock select signal received from outside the memory device, the test circuit generates an asynchronous signal from a clock received from the outside based on the delay value, and controls the peripheral circuit based on the asynchronous signal.
