Abstract
A state machine provides a power reducing capability by turning off a clock signal to a memory which stores the state of the state machine. Preferably, the state machine is connected to receive information from an external circuit, typically a system to be controlled by the state machine. The state machine includes a programmable memory in which each row stores a word representing output information as a sequence of bits. It also includes a register which stores the state of the state machine when the memory is not active. The state machine includes a selection circuit which selects a next state of the state machine. When the next state of the state machine is selected to be the same as the previous state the clock signal to the memory is turned off, enabling reduced power consumption by the state machine.
