Abstract
According to an example, a method for storage device reading may include receiving an input signal indicative of a period of oscillation of a ring oscillator coupled to a storage device of a plurality of storage devices, and measuring the period of oscillation of the ring oscillator by a time-to-digital circuit. The method for storage device reading may further include determining a value of data stored in the storage device based on the measurement.
Claims15
A method for storage device reading, the method comprising:
- receiving an input signal indicative of a period of oscillation of a ring oscillator coupled to a storage device of a plurality of storage devices;
- measuring the period of oscillation of the ring oscillator by a time-to-digital circuit;
- and
- determining a value of data stored in the storage device based on the measurement.
A storage device reading apparatus comprising:
- a time-to-digital circuit to receive an input signal indicative of a period of oscillation of a ring oscillator coupled to a storage device of a plurality of storage devices, and to measure the period of oscillation of the ring oscillator;
- and
- a priority encoder to determine a value of data stored in the storage device based on the measurement for an output of a series of flip-flops of the time-to-digital circuit to generate a binary value corresponding to the period of oscillation of the ring oscillator.
A non-transitory computer readable medium having stored thereon machine readable instructions for storage device reading, the machine readable instructions when executed cause a computer system to:
- receive an input signal indicative of a period of oscillation of a ring oscillator coupled to a storage device of a plurality of storage devices;
- measure the period of oscillation of the ring oscillator by a time-to-digital circuit by feeding the input signal to a series of buffers of the time-to-digital circuit, and feeding the input signal to a clock input of a flip-flop associated with each buffer of the series of buffers;
- and
- determine, by a processor, a value of data stored in the storage device based on the measurement.
