Abstract
An integrated circuit includes circuitry thereon which includes a sensor circuit which detects a change in one of the plurality of inputs to the integrated circuit and generates one or more pre-conditioning signals which control circuitry to set up voltages at various nodes in the integrated circuit to facilitate fast processing of data signals from inputs of the integrated circuit to outputs thereof. Embodiments of the sensor circuit include integrated memory circuits and integrated micro-processor circuits.
Claims12
A digital data processing circuit having therein a precharge node and having a plurality of inputs comprising:
- circuit means coupled to said input responsive to a signal applied at said input;
- look-ahead precharge circuit means coupled between plurality of said inputs to said digital data circuit and said precharge node and also coupled to said circuit means for detecting a change in a logic level of any of said inputs and precharging said precharge node in response to said change in said logic level;
- and
- wherein said digital data processing circuit is a read only memory including address buffer circuits, row and column decode circuits, and a digital storage array and wherein said precharge node is a sense bus in said data storage array.
