ABSTRACT:
A non-volatile counter circuit includes a state machine having a first input for receiving one or more control signals, a second input for receiving a current count value, a third input for receiving historical information, and an output for providing a next count value and an up/down control signal, and a non-volatile counter having an input coupled to the output of the state machine, and an output for providing a non-volatile count value. The non-volatile counter can be implemented onto a single integrated circuit using ferroelectric memory technology. The non-volatile counter circuit includes a first power supply node and a second power supply node for receiving power for operating the non-volatile-counter circuit through a first power supply or a second power supply, or both. The first and second power supplies can be low energy power supplies such as that provided by a sensor, or can be conventional power supplies. Either of the first and second power supplies can be internally boosted using an internal voltage doubler or other boosting circuitry.
