Abstract
In a charge-coupled SPS memory device, in which the transport takes place according to the 'pushing' principle, it may occur that during the SP transport charge is injected into the substrate and diffuses via the substrate into the memory mat. In order to avoid this undesired injection of charge, the input is provided with means by which it is ensured that the storage site under the input gate is entirely empty during the SP transport.
