Claims18
A semiconductor device comprising:
- memory blocks each having groups of memory cells that are connected to word lines;
- select gates for selecting the groups of memory cells;
- and
- an apply circuit that applies, at the time of reading data, a back bias to the select gates of unselected memory blocks.
A semiconductor device comprising:
- memory blocks each having groups of memory cells that are connected to word lines;
- and
- select gates that select the groups of memory cells,
- each select gate comprising a storage element.
A method of controlling a semiconductor device including memory blocks each having groups of memory cells connected to word lines, and select gates that select the groups of memory cells,
- the method comprising the steps of:
- selecting one of the memory blocks at the time of reading data;
- and
- applying a back bias to the select gates of unselected memory blocks.
A method of controlling a semiconductor device including memory blocks each having groups of memory cells connected to word lines, and select gates selecting the groups of memory cells,
- the method comprising the step of:
- programming the select gates.
A method of controlling a semiconductor device, comprising the steps of:
- precharging, at the time of reading data, a bit line running in memory blocks each having groups of memory cells connected to word lines, and select gates that select the groups of memory cells;
- and
- applying a back bias to the select gates of unselected blocks in a sensing period that follows a precharging period.
