EACH CIRCUIT PRODUCES A WRITE SIGNAL WHEN THE AMPLITUDES OF AN ANALOG SIGNAL AND ONE OF THE RAMP SIGNALS ARE EQUAL AND SIMULTANEOUSLY THE ASSOCIATED ONES OF THE TIMING SIGNALS ARE ABSENT IN THE RISE TIME OF SAID ONE OF SAID RAMP SIGNALS TO TRANSFER THE COUNT OF THE N LEAST SIGNIFICANT BINARY WEIGHTED STAGES OF AN (N+1) STAGE CODING COUNTER TO ASSOCIATED COLUMNS OF AN M-LINE, N-COLUMN MEMORY AND A READ SIGNAL WHEN THE ASSOCIATED ONES OF THE TIMING SIGNALS ARE PRESENT IN THE RISE TIME OF THE NEXT SUCCEEDING ONE OF SAID RAMP SIGNALS TO TRANSFER THE STORED CODE TO EXTERNAL CIRCUITS.
