ABSTRACT:
A series-parallel-series memory or other parallel-to-series CCD has charge-signals interlaced in alternate parallel channels 1a and 1b, and de-interlacing electrodes (19, 20, 21, 22) at the parallel-to-series transition. In order to avoid delay effects as a result of comb-shaped electrode configurations of the de-interlacing electrodes, and associated complex clock control, a narrow extra electrode (41) is provided between the de-interlacing electrodes and the series-output register (B). This electrode (41) may serve as a buffer electrode for each half row of information (from 1a or 1b) while the preceding half row (from 1b or 1a) is transported through the series output register.
