Abstract

An acoustic wave storage device capable of storing an acoustic surface wave signal for times of up to several milliseconds is described. The principle of the device is based on that of the acoustic surface wave convolver, with the information stored in surface states in silicon. It is expected that the storage time will ultimately be as much as 10–30 msec for signals with modulation frequencies of tens of megahertz. At the present time, we have seen storage of pulses approximately 0.4 μsec long for times of approximately 2 msec, but some of these early devices seem to be capable of yielding storage times as long as 7 msec.
