    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: A method and circuit arrangement for operating an information store, in particular a monolithic information store, whose storage cells and address circuits comprise bipolar transistors which are not continuously subjected to full power. The monolithic information store is readily fabricated by known planar process technology, has increased density, has reduced read/write times, reduced cycle time, and reduced power dissipation.
