Abstract: A transformer-coupled memory addressing circuit uses first and second groups of addressing transformers with each addressing input being applied to the primary winding of one of the transformers of the first group and all but one of the primary windings of the second group. Each primary winding of each transformer of the first group links a plurality of secondary windings equal in number to the number of transformers in the second group. Each of these secondaries of the first group then is connected in series with an oppositely-wound secondary from a different transformer in the second group, so that only when a secondary winding of the first group has current induced in it in the absence of current induced in its series-connected winding of the second group is the desired output obtained for a particular address.
