  • Publication number: 20240079067
    Abstract: A semiconductor memory device includes an output pin configured for connection with a memory controller, an output circuit configured to output through the output pin a voltage signal that changes over time in accordance with one or more bits of data to be output to the memory controller, and a control circuit configured to temporarily change a drive capability of the output circuit each time a voltage signal corresponding to one bit of the data is output through the output pin.

  • Publication number: 20100331540
    Abstract: A method for producing a compound having a deuterated aromatic ring or heterocyclic ring according to the invention includes heating a compound having an aromatic ring or heterocyclic ring in the presence of heavy water, a transition metal and a metal which generates deuterium. As the metal which generates deuterium, at least one metal selected from the group consisting of aluminum, magnesium, zinc, iron, lead and tin is preferred. As the transition metal, at least one metal selected from the group consisting of platinum, palladium, ruthenium and rhodium is preferred. The heating is preferably carried out by microwave irradiation.
