The string is scanned using an input clock signal to count the number of bits having a predetermined binary value. Each scan block includes a single latch to transfer the corresponding bit and to indicate reset. The scan blocks are organized into groups. Each group is enabled by a corresponding token signal. The token signal for each group is asserted after each preceding scan block indicates a pass value. When enabled by its token signal, the first scan block in a group is reset by a first clock signal. A second scan block in the group is enabled for reset after the first scan block indicates the pass value. The second scan block in the group is reset by a second clock signal having pulses that precede corresponding pulses from the first clock signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Scan chain circuits in non-volatile memory","description":"A bit scan circuit includes N scan blocks corresponding with an N-bit string of binary data.
