Abstract: An SPS CCD memory system is provided wherein a single tap, preferably a storage node, on an input serial or shift register is connected to the input of a plurality of parallel shift registers through a fan out circuit and the output of the plurality of parallel shift registers is connected to a single tap, preferably a storage node, on an output serial or shift register through a fan in circuit.

Abstract: A merged charge memory system is provided having an accessing arrangement wherein each of the word lines of the memory array is divided into a plurality of segments with cells associated only with a selected one or a portion of the segments being coupled at any particular time to bit driving and sensing means. Thus, only relatively few sense amplifiers compared with the number of bits per word of the array are required to handle all of the cells of the array. More particularly, in the merged charge memory system of the present invention, the flow of charges from charge source means is released only to the cells of the selected word segment or segments which are simultaneously coupled to bit driving and sensing means via associated bit/sense lines.
