Abstract
An SPS charge coupled device memory is described which is useful for storing video pictures. The memory avoids accumulation of charge below the de-interlacing electrodes controlling the transfer of data to the series output register by using two different procedures for generating the de-interlacing clocks for the odd channels and for the even channels of the parallel section. These procedures are carried out sequentially with an adjustable difference in time.
