Abstract
Regardless of data values stored on data memory cells, all read operations on the data memory cells are disallowed. For example, current flow is disallowed through a string of the data memory cells and one or more select line memory cells. The particular select value stored in a first select line memory cell in the string, for example coupled to a ground select line or a string select line, determines whether the string is enabled or disabled.
