MEMORY SYSTEM EMPLOYING CAPACITANCE STORAGE MEANS

摘要: Memory apparatus is disclosed wherein digital information in the form of message units stored capacitance arrays. Each unit converted to an M-level voltage determined by bit content and transferred individual for storage; once has been stored, power system can be removed. Appropriately programmed switching enables storage many sequentially upon capacitances. Small physical size requirements memory preferred uses as well reliability switch are met field effect transistors which, however, allow charge leakage from It necessary, therefore, that periodically updated or restored. Updating effected feeding signals on capacitances individually one input a comparator other thereof analog signal representing lowest number bits greater than equal represented displayed particular capacitance. The thus then connected and/or which derived passed readout device. uses, image pickup solid state camera, discussed detail.
