Abstract:
A controller for controlling a generator system on a memory chip, the controller operating as a state machine in accordance with a state diagram including a plurality of X states, and comprising:an evaluation arrangement for evaluating a combination of only a predetermined one of a plurality of N input signals from remote devices and only a predetermined one of a plurality of X state signals indicating a current state in the state diagram for the controller at any instant of time, and generating a separate predetermined one of a plurality of Y output signals having a predetermined logical value which is different than that of the remaining plurality of Y output signals for indicating that a change from one state to a next state in the state diagram is to be made when the predetermined one of the plurality of N input signals and the predetermined one of the plurality of X state signals comprise a predetermined logical condition;a state storage device which in responsive to the predetermined one of a plurality of Y output signals having a predetermined logical value from the evaluation arrangement generates a revised plurality of X state output signals for transmission to the evaluation arrangement indicating a change in the state diagram from a current state to a next state of the plurality of X states; andan output arrangement responsive to the revised plurality of X state output signals from the state storage device for generating separate predetermined ones of M output signals associated with said next state for controlling the generator system.
