Abstract: In one embodiment, a semiconductor storage device includes a plurality of memory chips, at least one of the memory chips including a first controller configured to be shifted to a wait state of generating a peak current, before generating the peak current in accordance with a command. The device further includes a control chip including a second controller configured to search a state of the first controller and control, based on a result of searching the state of the first controller, whether or not to issue a cancel instruction for the wait state to the first controller that has been shifted to the wait state.

Abstract: An aromatic odorant emitting device comprising a mainbody case and a cover case, said device including an odorant, and an evaporator immersed with the aromatic odorant, and a fan unit which blows the air to the evaporator so as to control the evaporation rate of the odorant in response to the temperature and the illumination intensity in the room, with the aid of a thermosensor and a photosensor, so that a constant aromatic odorant evaporation is provided.
