Abstract
A multilevel analog recording and playback system is described. An analog processing circuit processes analog data. A storage circuit includes a non-volatile memory array, a switching circuit, and a communication interface. The non-volatile memory array stores analog and digital data. The switching circuit transfers the analog and digital data to and from the memory array. The communication interface allows a processor to exchange information with the device.
