    Abstract: An improved method of operating a monolithic memory together with novel and efficient circuitry for practicing said improved method is disclosed. In a bipolar transistor store, or monolithic memory, in accordance with the invention, a very low current (first level) flows from the load elements to the internal cell nodes in the stand-by mode. During the initial portion of a read cycle, current flows from the bit lines to the cell nodes, in addition to the stand-by current (second level). In the recovery period of the read cycle or write cycle a short pulse is added to the stand-by current (third level), thereby reducing the recovery time. The practice of the invention provides a monolithic memory having minimal power requirements and a substantially reduced cycle time.

    Abstract: The invention relates to a monolithically integrated semiconductor arrangement with at least one integrated injection logic (I2L) structure including an injection zone and an inverting transistor, the injection zone, and lateral thereto, the transistor base zone of a same first conductivity type being arranged in a semiconductor layer of a second conductivity type, which forms the emitter zone of the transistor, the transistor being completed by a collector zone of the second conductivity type, which is formed in the base zone, and the I2L structure being surrounded at least partly by a separating zone introduced at a predetermined spacing into the semiconductor layer. The injection zone and the transistor base zone in the region of their edges facing each other are extended up to or into the separating zone, while in the region of their remaining edges they are spaced therefrom at the predetermined distance. The invention further relates to a storage arrangement having storage cells including two such I2L structures each which are cross-coupled in the manner of a flip-flop.
