摘要
A new bias pulse method was proposed to suppress read disturbance in unselected strings of 3-D stack NAND flash memories. Using the proposed read method, we could suppress effectively a large cell V-th shift generated by boosting hot carrier injection. As a result, the cell V-th shift in unselected string is quite similar to normal read disturbance in select string. The proposed read method was verified by both measurement and simulation.
