Claims17
A semiconductor device comprising:
- groups of memory cells that are connected to word lines;
- and
- select gates that are controlled by control word lines and are connected to the groups of memory cells, each of the select gates being capable of storing protection information for a respective one of the groups of memory cells.
A method of controlling a semiconductor device, comprising the step of
- writing protection information into a select gate that is connected to a group of memory cells and a control word line, the protection information indicating protection of the group of memory cells.
Dependencies are inferred from the claim text.
