Abstract:
A storage cell of an integrated circuit operable in a radiation environment to capture and store at predetermined time intervals a time sample of a data input signal, a signal representative of the stored data sample for each time interval being generated at an output of said storage cell, said storage cell comprising:at least three data capturing circuits, each having a data input coupled to the data input signal and operable to capture and store a time sample of the data input signal at each predetermined time interval, the stored data sample of each said circuit being generated correspondingly at an output thereof; means coupled to the outputs of said data capturing circuits for generating at the output of said storage cell a signal representative of a stored data sample selected from at least two of said circuit outputs; and means coupled to said data capturing circuits for causing each data capturing circuit to capture a different time sample of the input data signal from the other data capturing circuits over each predetermined time interval.
