MOSFET decoder circuit configuration for enhancing read/only storage memory densities by providing decoded output lines on a narrower pitch than conventional decoder circuits, thereby, increasing the number of decoded lines of the conventional decoder. In addition, the number of conventional decoder circuits required are reduced by a binary factor, thereby decreasing power requirements. Decoded line capability is increased by means of properly addressed array select devices whereby the number of array select devices required is equal to the particular binary factor utilized. For particular physical layout ground rules utilized in fabrication of an integrated decoder of the instant invention, the binary factor is chosen so that the decoder pitch is equal to the read/only storage memory pitch in order to obtain maximum chip density. |
