Abstract

PURPOSE:To obtain an infromation rewiting device featuring a high efficiency and low cost for the information rewriting at more than one memory part, by providing the selection part to select to which memory part the rewriting information is to be given and applying both the selection and control signals. CONSTITUTION:When the signal of ''1'' is supplied to control order signal terminal 23, the output level becomes ''1'' for either one of AND gates 16-16''' of the block whose contents is rewritten by the indications of fields 28-31 added to order code 27 from field signal terminals 24-24''' corresponding to fields 28-31. As a result, AND gate 18 of the block becomes ''0'', and the memory contents of control memory element 20 is never delivered. Furthermore, AND gate 17 features the signal level in accordance with the information of information bus 22, and the contents of bus 22 is written into memory element 20 through OR gate 19. Thus, the contents can be rewritten with the necessary memory elements only and without increasing the control order memory device.
