A device for generating k-bit parallel pseudo-random data includes “n” registers, from the first through the n-th registers (“n” is an integer not less than 3), and “k” exclusive-OR gates, from the first through the k-th exclusive-OR gates (“k” is an integer not less than 2). An output of the m-th register is input to the (m+k)th register (“m” is an integer between 1 and (n−k)). Outputs of the first through the (k−1)th exclusive-OR gates are respectively input to the second through the k-th exclusive-OR gates. An output of the first register is input to the first exclusive-OR gate. The outputs of the first through the k-th exclusive-OR gates are respectively input to the k-th through the first registers. Outputs of “k” registers, from the (n−k+1)th through the n-th registers are respectively input to the k-th through the first exclusive-OR gates, and also extracted as the k-bit parallel pseudo-random data.
