Abstract
A random number generator comprising a counter circuit configured to be supplied with a clock signal and a random signal, and to provide a count value of the clock signal with respect to a transition of the random signal, and a first latch circuit configured to latch the count value with respect to the transition of the random signal, and to provide a first random number signal.

A random number generator comprising:
- a counter circuit configured to be supplied with a clock signal and a random signal, and to provide a count value of the clock signal with respect to a transition of the random signal;
- and
- a first latch circuit configured to latch the count value with respect to the transition of the random signal, and to provide a first random number signal.
A random number generator comprising:
- an AND circuit configured to be supplied with a random signal and a clock signal, and to generate a logic product of the random signal and the clock signal;
- a dividing latch circuit configured to provide alternately a high level signal and a low level signal with respect to the logic product output;
- and
- a first latch circuit configured to latch the count value with respect to a transition of the random signal, and to provide a random number signal.
