Counter for cross-tie wall memory system

A counter for a cross-tie wall memory system, comprising:

• a straight-edged electrically conductive stripline means;
• magnetic data track means insulatively superposed said stripline means for forming successive memory cells therealong;
• generator means including an electrically conductive layer that is superposed a generator memory cell in said data track means at a first end thereof for selectively generating a cross-tie in said generator memory cell;
• detector means including two electrically conductive lines that are superposed a detector memory cell in said data track menas at a second end thereof for forming a gap therebetween that is centered about said detector memory cell, said generator means and said detector means sandwiching N-1 memory cells therebetween;
• replicator means coupling successive replicate drive field sequences to said data track means for replicating said selectively generated cross-tie in said generator memory cell, through said data track means and into said detector memory cell;
• read out means coupling a read drive current signal across said detector memory cell for detecting the presence or absence of a cross-tie in said detector memory cell and generating a corresponding Output signal indicating the presence or absence of a cross-tie in said detector memory cell;
• and,
• means responsive to said Output signal for coupling a Clear drive field to said data track means for annihilating all of the cross-ties replicated in said data track means and generating a signal indicating that N successive ones of said replicate drive field sequences have occurred since the generation of said selectively generated cross-tie in said generator memory cell.
