摘要:
A memory wherein any “disturb effect” can be suppressed in which data in unselected memory cells are lost. This memory has a memory cell array(1) including bit lines, word lines, which are disposed to intersect the bit lines, and memory cells(12) each connected between bit and word lines. In this memory, an access operation, which includes at least one of read, rewrite and write operations, is made to a selected memory cell(12). During this access operation, it is performed to apply to the memory cell(12) a first voltage pulse, which provides an electrical field in a first direction so as to invert a stored data, and a second voltage pulse, which provides as electrical field in the opposite direction to the first one so as not to invert the stored data. In addition, a recovery operation for recovering a residual polarization amount is made to the memory cell(12).

摘要:
A memory capable of suppressing reduction of a reading voltage in data reading regardless of dispersion in a manufacturing process is provided. This memory comprises charge storage means, a first field-effect transistor and data determination means. The memory sets a voltage between a control terminal and a remaining first terminal of the first field-effect transistor to a threshold voltage for bringing the first field-effect transistor into an OFF-state in the vicinity of a boundary state between ON- and OFF-states through the threshold voltage of the first field-effect transistor.
