Abstract
In a controller for controlling a generator system on a memory chip, the controller operates as a state machine in accordance with a state diagram including a plurality of N states. A state storage device is responsive to input signals from a transition arrangement including a 1-out-of-N code indicating a change in the state diagram from a current state to a next state of the plurality of N states. The state storage device generates a revised plurality of N state output signals comprising a true State signal and a complementary true State signal for the next state of the plurality of N states. The state storage device is also responsive to an asynchronous Reset signal received from an external source for generating a Reset and a complementary Set output signal. A state identification circuitry is responsive to a selectively applied activation signal for inhibiting the output of the revised plurality of N state signals from the state storage device and sequentially reading out the plurality of N state signals currently stored in the state storage device. The the 1-out-of N-code forming the plurality of N state signals are used to determine which state of the state diagram the controller is presently in when the controller fails to complete a procedure in the state diagram.
