MULTIPLE MESSAGE MULTILEVEL ANALOG SIGNAL RECORDING AND PLAYBACK SYSTEM HAVING MEMORY ARRAY CONFIGURABLE FOR ANALOG AND DIGITAL STORAGE AND SERIAL COMMUNICATION

摘要

A multilevel analog recording and playback system isdescribed. An analog processing circuit processes analog data.A storage circuit includes a non-volatile memory array, aswitching circuit, and a communication interface. The non-volatile memory array stores analog and digital data. Theswitching circuit transfers the analog and digital data to andfrom the memory array. The communication interface allows aprocessor to exchange information with the device.
