Abstract
An apparatus and method for providing a source of random numbers are generally described. In one example, an apparatus includes one or more storage elements having a selected voltage and a trip point, the voltage being close enough to the trip point such that random telegraph signal (RTS) noise associated with the elements is a determinant of whether the read voltage is above or below the trip point.
Claims14
An apparatus comprising:
- One or more storage elements having a selected voltage and a trip point, the voltage being close enough to the trip point such that random telegraph signal (RTS) noise associated with the elements is a determinant of whether the read voltage is above or below the trip point.
A method comprising:
- selecting a voltage for one or more storage elements having a trip point, the selected voltage being close enough to the trip point such that random telegraph signal (RTS) noise associated with the elements is a determinant of whether the read voltage is above or below the trip point;
- generating one or more bits having values that are highly influenced by RTS noise;
- and
- using a number of the generated bits to provide a source of random numbers.
