Protecting data from decryption from power signature analysis in secure applications

A universal logic array with variable circuit topology comprising:

• a plurality of array elements where each array element includes a first set of MOSFET devices with a p-channel type configuration and a second set of MOSFET devices with an n-channel type configuration;
• and
• at least one of a metallization layer and a via connection to form an interconnection between one or more of the first set of MOSFET devices and the second set of MOSFET devices in at least one of the array elements to produce a circuit topology to implement at least one of a Boolean function and a chaotic function and a logic function, and
• at least one cell as defined by the circuit topology within each of at least two array elements combined with additional interconnections formed by the metallization layer and the via connection between the two array elements, wherein the at least one cell comprises:
• a logic gate cell receiving at least one input and outputting a logic level signal including a logical ONE or a logical ZERO according to a function of the logic gate cell, and
• a current feedback path from an output of the logic gate cell to adjust a supply current to the logic gate cell in order for the supply current to remain substantially constant during a transition from the logical ONE to the logical ZERO and during a transition from the logical ZERO to the logical ONE.
