Abstract :
An acoustic-surface-wave memory is described, operating at a bit rate of 220 MHz and storage capacity of 1280 bit per recirculation loop. The transducers are coded using orthogonal pairs of Golay complementary sequences to obtain pulse-in pulse-out behaviour. The recirculation electronics uses standard commercial logic for both the amplifier and the WRITE, READ, INHIBIT and RECLOCKING functions.
