Abstract:
1. A storage circuit having a normal mode for receiving and storing an external bit value and a random number generation mode, said storage circuit comprising: a bit value storage circuit having an input node for receiving an input bit value from outside said bit value storage circuit and an output node for outputting an output bit value; wherein said bit value storage circuit is configured such that: (i) when said storage circuit is operating in said normal mode, said bit value storage circuit generates at said output node as said output bit value a stable output bit value corresponding to said external bit value; and (ii) when said storage circuit is operating in said random number generation mode, said bit value storage circuit generates at said output node an oscillating output bit value and a change from said random number generation mode to said normal mode leaves said output bit value as a stable pseudo random bit value.
