METHOD AND APPARATUS FOR A FLEXIBLE CONTROLLER INCLUDING AN IMPROVED OUTPUT ARRANGEMENT FOR A DRAM GENERATOR SYSTEM

摘要

In a controller (100) 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 X states. A state storage device (106) is responsive to input signals indicating a change in the state diagram from a current state to a next state for generating a revised plurality of X state output signals comprising a true State signal and a complementary true State signal for the next state of the plurality of X states. An output arrangement (108) is responsive to the true State signal and the complementary true State signal in 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 while providing substantially zero current consumption when the state diagram reaches a final state of the plurality of X states.
