ABSTRACT:
A memory system for analogue data includes a plurality of semiconductor charge device shift registers integrated on a semiconducor substrate. In one embodiment analogue data is serially inputed into a charge-coupled device (CCD) shift register. The serial data is converted to parallel and propagates at a substantially slower speed through a plurality of shift registers. A parallel-to-serial conversion provides a serial readout of the data. The serial-parallel-serial arrangement of the memory significantly reduces the number of transfers required to propagate one bit of data through the memory and provides correspondingly improved outputs. In a different aspect of the invention, a plurality of bits of digital data are transformed into a single analogue signal effecting a reduction in size of the memory for equal storage capability.
