ABSTRACT:
There is provided a bit refresh circuit and method of checking errors in bit values of a register and refreshing the bit values, and an integrated circuit comprising the bit refresh circuit. The integrated circuit includes a refresh unit checking whether or not the bit values of the register storing data used to control the operations of a logic circuit changes due to external noise. The refresh unit checks bit-by-bit whether or not there are errors in the bit values due to the external noise. If there are errors in the bit values of the register, the data of the associated bit values stored in a memory are refreshed into the register.
