  • Publication number: 20070138530
    Abstract: An integrated circuit having a memory cell and/or memory cell array including a plurality of memory cells (as well as techniques for reading, controlling and/or operating, the memory cell, and/or memory cell array). Each memory cell includes at least one transistor having an electrically floating body transistor and an active access element. The electrically floating body region of the transistor forms a storage area or node of the memory cell wherein an electrical charge which is representative of a data state is stored in the electrically floating body region. The active access element is coupled to the electrically floating body transistor to facilitate programming of the memory cell and to provide a relatively large amount of majority carriers to the storage area or node of the memory cell during a write operation.

  • Publication number: 20070109896
    Abstract: A data storage device such as a DRAM memory having a plurality of data storage cells 10 is disclosed. Each data storage cell 10 has a physical parameter which varies with time and represents one of two binary logic states. A selection circuit 16, writing circuits 18 and a refreshing circuit 22 apply input signals to the data storage cells to reverse the variation of the physical parameter with time of at least those cells representing one of the binary logic states by causing a different variation in the physical parameter of cells in one of said states than in the other.

    Abstract: There are many inventions described and illustrated herein. In one aspect, the present invention is directed to a memory cell, architecture, and/or array and/or technique of writing or programming data into the memory cell (for example, a technique to write or program a logic low or State “0” in a memory cell employing an electrically floating body transistor. In this regard, the present invention programs a logic low or State “0” in the memory cell while the electrically floating body transistor is in the “OFF” state or substantially “OFF” state (for example, when the device has no (or practically no) channel and/or channel current between the source and drain).

  • Patent number: 7085153
    Abstract: There are many inventions described and illustrated herein. In a first aspect, the present invention is directed to a memory cell and technique of reading data from and writing data into that memory cell. In this regard, in one embodiment of this aspect of the invention, the memory cell includes two transistors which store complementary data states. That is, the two-transistor memory cell includes a first transistor that maintains a complementary state relative to the second transistor. As such, when programmed, one of the transistors of the memory cell stores a logic low (a binary “0”) and the other transistor of the memory cell stores a logic high (a binary “1”). The data state of the two-transistor complementary memory cell may be read and/or determined by sampling, sensing measuring and/or detecting the polarity of the logic states stored in each transistor of complementary memory cell.

  • Publication number: 20060131650
    Abstract: A technique of 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 embodiment, the present inventions are directed to a memory cell, having an electrically floating body transistor, and/or a technique of reading the data state in such a memory cell. In this regard, the present inventions employ the intrinsic bipolar transistor current to read and/or determine the data state of the electrically floating body memory cell (for example, whether the electrically floating body memory cell is programmed in a State “0” and State “1”). During the read operation, the data state is determined primarily by or sensed substantially using the bipolar current responsive to the read control signals and significantly less by the interface channel current component, which is negligible relatively to the bipolar component.
