摘要： A dynamic type semiconductor memory device includes m memory blocks each having a plurality of memory cells, and a plurality of sense amplifier groups associated with the respective memory blocks. Each sense amplifier group senses and amplifies data of a selected memory cell in the related memory block. The memory device further includes a circuit for generating a refresh instruction detecting signal in response to an externally applied refresh mode indicating signal, and circuitry responsive to a block designating signal and the refresh instruction detecting signal for activating each of the sense amplifier groups in such a manner that only start timings for the sensing operations of the sense amplifier groups related to the designated memory blocks may differ from each other. This activation circuitry activates the respective sense amplifier groups related to the memory blocks designated by the block designating signal in such a manner that their sensing operations may have the same start timing in the normal mode. This device significantly reduces current dissipation in the refresh mode, while the access time in the normal mode is not adversely affected. This device is suitable for use as an internal memory of a battery back-up type computer because of its small load on the battery.

摘要： Provided is an organic EL element which withstands mass production of organic EL display panels, and promises driving at a low voltage and high luminous efficiency due to excellent hole-injection efficiency. Specifically, an organic EL element is formed by sequentially laminating an anode, a hole injection layer, a buffer layer, a light-emitting layer, and a cathode on one surface of a substrate. The hole injection layer is a at least 2 nm thick tungsten oxide layer formed under predetermined film forming conditions, and includes an occupied energy level that is 1.8 eV to 3.6 eV lower than a lowest energy level of a valence band of the hole injection layer in terms of a binding energy. This reduces the hole injection barrier between the anode and the hole injection layer and the hole injection barrier between the hole injection layer and the buffer layer.
