An integrated circuit device (for example, logic or discrete memory device) comprising a memory cell including a punch-through mode transistor, wherein the transistor includes a source region, a drain region, a gate, a gate insulator, and a body region having a storage node which is located, at least in part, immediately beneath the gate insulator. The memory cell includes at least two data states which are representative of an amount of charge in the storage node in the body region. First circuitry is coupled to the punch-through mode transistor of the memory cell to: (1) generate first and second sets of write control signals, and (2a) apply the first set of write control signals to the transistor to write a first data state in the memory cell and (2b) apply the second set of write control signals to the transistor to write a second data state in the memory cell. In response to the first set of write control signals, the punch-through mode transistor provides at least the first charge in the body region via impact ionization. The transistor may be disposed on a bulk-type substrate or SOI-type substrate.

A technique of writing, programming, holding, maintaining, sampling, sensing, reading and/or determining the data state of a memory cell of a memory cell array (for example, a memory cell array having a plurality of memory cells which consist of an electrically floating body transistor). In one aspect, the present inventions are directed to techniques to control and/or operate a semiconductor memory cell (and memory cell array having a plurality of such memory cells as well as an integrated circuit device including a memory cell array) having one or more electrically floating body transistors in which an electrical charge is stored in the body region of the electrically floating body transistor. The techniques of the present inventions may employ bipolar transistor currents to control, write and/or read a data state in such a memory cell. In this regard, the present inventions may employ a bipolar transistor current to control, write and/or read a data state in/of the electrically floating body transistor of the memory cell.

摘要:
A technique of sampling, sensing, reading and/or determining the data state of a memory cell (of, for example, a memory cell array) including an electrically floating body transistor. In this regard, the intrinsic bipolar transistor current component is employed to read and/or determine the data state of the electrically floating body memory cell. During the read operation, the data state is determined primarily by or read (or sensed) substantially using the bipolar current component responsive to the read control signals and significantly less by the interface channel current component, which is negligible relative to the bipolar component. The bipolar transistor current component may be very sensitive to the floating body potential due to the high gain of the intrinsic bipolar transistor of the electrically floating body transistor. As such, the programming window obtainable with this reading technique may be considerably higher than the programming window employing a conventional reading technique (which is based primarily on the interface channel current component).

The electrically floating body transistor may be disposed on a bulk-type substrate or SOI-type substrate.
