Integrated circuit with analog or multilevel storage cells and user-selectable sampling frequency

An integrated circuit comprising:

• an array of memory cells;
• a write circuit to write data into the memory cells using a sampling rate;
• and
• an oscillator capable of generating a clock output of two or more different frequencies based on a user value stored within the integrated circuit, wherein the sampling rate is based on the frequency of the clock output.

A method of operating an integrated circuit comprising:

• providing an input waveform to the integrated circuit;
• selecting a sampling frequency for sampling the input waveform by storing a user value in the integrated circuit;
• sampling the input waveform;
• sampling the input waveform at the selected sampling frequency;
• and
• storing samples of the input waveform in memory cells of the integrated circuit.
