<p>Techniques are present for locating an initial physical location in a looping shift register with random skips on each loop. Here the shift register is for accessing columns in a non-volatile memory, where defective columns of the array are skipped. A look-up table provides for the initial skip of each loop, providing the number of skips from preceding loop to provide a physical address is close to the actual physical address. A new structure of shift registers then enables an automatic shift mode within the loop. The new structure has an additional register and logic gates that count how many skipped entry before the current pointer and shift the current pointer accordingly.</p> |
