A memory array is characterized by a threshold definition, which includes threshold voltage ranges representing data values stored by a part of the memory array, and a set of sense windows separating the threshold voltage ranges. The threshold definition is varied, responsive to at least one of program operations and erase operations. Such operations change a distribution of the data values stored in the memory group.

The storage layer such as a nitride layer of a nonvolatile memory cell has two storage parts storing separately addressable data, typically respectively proximate to the source terminal and the drain terminal. The applied drain voltage while sensing the data of one of the storage parts depends on the data stored at the other storage part. If the data stored at the other storage part is represented by a threshold voltage exceeding a minimum threshold voltage, then the applied drain voltage is raised. This technology is useful in read operations and program verify operations to widen the threshold voltage window.

A memory and an operating method thereof are provided therein. When searching a boundary of a threshold voltage distribution of the memory, data errors resulted from tail bits of the memory would be corrected. Therefore, a sensing window could be broader, and the boundary of the threshold voltage distribution could be determined precisely.

A sense amplifier comprises a sense node, a reference node, a memory input stage circuit, a reference input stage circuit, an output stage circuit, and a shielding circuit. The memory input stage circuit comprises first input node for maintaining a first sense voltage established by a cell current and establishes a second sense voltage on the sense node in response to the first sense voltage. The reference input stage circuit comprises an output node and a second input node, which is for maintaining a first reference voltage established by the reference current and establishes a second reference voltage on the reference node in response to the first reference voltage. The output stage circuit obtains a sense result in response to the second reference voltage and the second sense voltage. The first shielding circuit shields the output node from being interfered with the second reference voltage on the reference node.
