Abstract
The present invention is a high density integrated circuit analog signal recording and playback system. The recording and playback system is based upon an array storing analog signals. The array has rows and columns of non-volatile memory cells to store the signal information. Analog column read/write circuitry is used to both store the analog information and retrieve it on a real time basis, using interleaving of analog information on a plurality of sample/hold circuits prior to storage in the array to increase throughput.
