Abstract

An interface of a memory circuit includes a chip enable terminal, at least one data terminal, and a data strobe terminal. The chip enable terminal receives a chip enable signal that varies between a first high voltage and a low voltage. The at least one data terminal receives a first data signal that varies between a second high voltage and the low voltage during a command phase, and transmits or receives a second data signal during a data phase. The data strobe terminal receives a first data strobe signal that periodically varies between the second high voltage and the low voltage during the command phase, and transmits or receives a second data strobe signal that swings periodically during the data phase. During a transition interval between the command phase and the data phase, the data strobe terminal stops receiving or transmitting data strobe signals that swing periodically.
