Abstract
An apparatus for storing digital data includes a clock pulse source and plural serial shift register stages storing data bits. Digital data signals, each having plural databits, are coupled to and shifted in the stages in synchronization with the clock pulses. Data stored in the memory stages stages are held in a non-erasable memory unit provided for each stage while an emergency causing a failure of a power supply of the shift register occurs.
