Abstract: A storage element for use in a logic array including a flip-flop device and a complex logic circuit interconnected in such a way that the output of the complex logic circuit is an input to the flip-flop. A Toggle Flip-Flop Control (TFFC) signal, an invert control (INV) signal, and a clock (CLK) signal are also inputs to the complex logic circuit. The output of the flip-flop connects to an output pad, an internal direct feedback line which is one of the means by which the flip-flop is connected to the comples logic circuit, and an external feedback bus which leads back to an associated AND-OR array. The inptu to the complex logic circuit is generated by the standard AND-OR array which is programmable to some degree.
