Abstract
A coding technique and circuit implementation for reducing the number of electrical contacts to a memory device, which memory device is configured as part of a monolithic structure. Memory selection is achieved by changing at least one characteristic of a clock signal, such as pulse width. A read or write operation is selected by a mode selector, the level of which is determined by the level of the signal on a function contact when memory selection is achieved.
