ABSTRACT:
A digital multibit non-volatile memory integrated system includes autozero multistage sensing. One stage may provide local sensing with autozero. Another stage may provide global sensing with autozero. A twisted bitline may be used for array arrangement. Segment reference may be used for each segment. The system may read data cells using a current sensing one or two step binary search. The system may use inverse voltage mode or inverse current mode sensing. The system may use no current multilevel sensing. The system may use memory cell replica sensing. The system may use dynamic sensing. The system may use built-in byte redundancy. Sense amplifiers capable of sub-volt (<<1V) sensing are described.
