    摘要: While the supply of power is stopped, a data signal that has been held in a volatile memory section can be held in a nonvolatile memory section. In the nonvolatile memory section, a transistor having an extremely low off-state current allows a data signal to be held in the capacitor for a long period of time. Thus, the nonvolatile memory section can hold the logic state even while the supply of power is stopped. When the supply of power is started again, the data signal that has been held in the capacitor while the supply of power has been stopped is set at such a potential that malfunction does not occur by turning on the reset circuit.

    摘要: A signal processing circuit using a nonvolatile memory circuit with a novel structure is provided. The nonvolatile memory circuit is formed using a transistor including an oxide semiconductor and a capacitor connected to one of a source electrode and a drain electrode of the transistor. A high-level potential is written to the memory circuit in advance, and this state is kept in the case where data to be saved has a high-level potential, whereas a low-level potential is written to the memory circuit in the case where data to be saved has a low-level potential. Thus, a signal processing circuit with improved writing speed can be provided.

    摘要: The present disclosure includes methods, and circuits, for operating a memory device. One method embodiment for operating a memory device includes controlling data transfer through a memory interface in an asynchronous mode by writing data to the memory device at least partially in response to a write enable signal on a first interface contact, and reading data from the memory device at least partially in response to a read enable signal on a second interface contact. The method further includes controlling data transfer in a synchronous mode by transferring data at least partially in response to a clock signal on the first interface contact, and providing a bidirectional data strobe signal on an interface contact not utilized in the asynchronous mode.

    摘要: An object is to provide a signal processing circuit which can be manufactured without a complex manufacturing process and suppress power consumption. A storage element includes two logic elements (referred to as a first phase-inversion element and a second phase-inversion element) which invert a phase of an input signal and output the signal, a first selection transistor, and a second selection transistor. In the storage element, two pairs each having a transistor in which a channel is formed in an oxide semiconductor layer and a capacitor (a pair of a first transistor and a first capacitor, and a pair of a second transistor and a second capacitor) are provided. The storage element is used in a storage device such as a register or a cache memory included in a signal processing circuit.
