Abstract: An integrated circuit structure is described which includes a base semiconductor structure and a programmable semiconductor structure which are fabricated separately and later joined to form the integrated circuit structure. The base semiconductor structure includes conventional semiconductor devices fabricated in accordance with a first set of design rules. The programmable semiconductor structure includes programmable elements fabricated in accordance with a second set of design rules which may be different than the first set of design rules. The programmable elements are used to control the configuration of the integrated circuit structure or to provide field programmable devices for use in the integrated circuit structure.

Abstract: An electronic game having a capability to vary the probabilities of events happening to simulate choices that are made in actual games. A baseball electronic game is specifically described having a miniature baseball field representation with lights indicating positions of runners on the bases and a score board. The disposition of each batter is determined by random electronic generator. The batting average resulting from the generator can be altered for a short period of time by the players selecting a relief pitcher mode or a pinch hitter mode for one or a few batters and only for a few times during each game.
