摘要： A conductor-insulator-semiconductor (CIS) structure for a random access surface charge memory system is disclosed. The memory system comprises an array of memory cells including charge storage regions, charge transfer regions and charge receive-source regions formed along the surface-adjacent portions of a semiconductor substrate. A charge-storage line insulatingly overlies the storage regions of a row of memory cells and a bit line, comprising an extended region of opposite-conductivity-type, interconnects the receive-source regions of the same memory cells. Addressing in the Y-direction (word selection) is provided by charge transfer lines insulatingly overlying the charge transfer regions of a column of memory cells. Selected memory cells are addressed for read and write purposes by first activating the word select line which makes available one cell in each row of the memory. The desired row is then selected by means external to the array of memory cells. All cells of the selected word line are refreshed, but only one cell is addressed for read and write purposes. Means for reading, writing and refreshing data in the memory system are also disclosed.

摘要： In a charge transfer transversal filter a semiconductor substrate is provided with main and parallel portions. A group of serially arranged electrodes insulatingly overlie and are uniformly spaced from the channel portions. The electrodes form with the substrate a plurality of stages of first and second charge transfer shift register over the main and parallel channel portions of the substrate, respectively. One electrode of each of the stages of the shift registers has a split along the length dimension thereof over the main channel portion dividing each of the one electrodes over the main channel portion into a first part and a second part with a third part overlying the parallel channel portion. The first parts of the one electrodes are connected to a first conductive line and the second and third parts of the one electrodes are connected to a second conductive line. The area of the first parts of the one electrodes being equal to the sum of the areas of the second and third parts of the one electrode.

A high absolute level of a waveform applied to a second electrode of a cell causing charge in the first storage region thereof to transfer to the second storage region thereof and a low absolute level of the waveform applied to a second electrode of a cell causing charge in the second storage region thereof to transfer to the first storage region thereof. Each of the waveforms has a low absolute level during a first subperiod and an absolute level which is either high or low during a second subperiod in response to a respective reference signal, whereby charge in each cell is transferred between the first and second charge storage regions thereof in a time sequence determined by a respective reference signal. Means are provided connected in circuit with the first storage electrodes for sensing the total net charge transferred to and from the first charge storage regions during a common period of the voltage waveforms.
