  • Publication number: 20020093848
    Abstract: A magneto resistive memory contains first switches, a word line voltage source generating a word line voltage connected to the first switches, a line node, second switches, and cells formed of cell resistors each having a first terminal connected to the word line voltage through one of the first switches and a second terminal connected to the line node through one of the second switches. A reference resistor is connected to the line node and a reference voltage source is connected to the reference resistor. The reference resistor with the reference voltage source brings about a reduction in a respective cell current, flowing from the line node, by an average current. A device is connected to the line node and evaluates the cell resistors. The device has an amplifier for converting a difference between the respective cell current and the average current into a voltage functioning as an evaluation signal.

  • Publication number: 20020071306
    Abstract: A magnetoresistive memory is described and contains a common word line voltage source, bit lines, word lines crossing the bit lines, and a memory cell array having memory cells with cell resistors. The memory cell array further has reference cells with reference cell resistors. The memory cell array is configured such that for testing a respective cell resistor in each case two of the reference cell resistors nearest the respective cell resistor and the reference cell are simultaneously connected to a common word line voltage. A first feedback amplifier together with the two reference cell resistors form a summing amplifier. A second feedback amplifier together with the respective cell resistor form an amplifier having an equivalent gain as the summing amplifier. A comparator is connected to the summing amplifier and the amplifier. The comparator has an output supplying an evaluation signal dependent on the respective cell resistor.

  • Publication number: 20020024854
    Abstract: A description is given of a sense amplifier subcircuit (10), for example an N latch section or a P latch section, for a DRAM memory for amplifying voltage signals read from a bit line (50), having at least two evaluation transistors (20; 30), the gate (21) of one evaluation transistor (20) being connected or connectable to at least one bit line (50) and the gate (31) of another evaluation transistor (30) being connected or connectable to at least one reference bit line (51) and the drains (23, 33) of the evaluation transistors (20; 30) being connected or connectable to the bit lines (51, 50) and the sources (22, 32) of the evaluation transistors (20; 30) being connected or connectable to a (NCS/PCS) lead (11). According to the invention, at least one of the evaluation transistors (20; 30) is designed in such a way that its threshold voltage changes dynamically during the evaluation operation by virtue of the change in the gate voltage being coupled to a change in the body voltage.

  • Publication number: 20010030884
    Abstract: As a consequence of DRAM memory cell miniaturization, the available space for read/write amplifiers decreases in width from hitherto 4 bit line grids to 2 bit lines grids. Conventionally previously known read/write amplifiers cannot be accommodated on this reduced, still available space. Therefore, it has not been possible hitherto to provide read/write amplifiers arranged beside one another which would manage with the novel DRAM memory cell spacings. The principle underlying the invention is based on replacing at least some of the transistors of conventional design which are usually used for read/write circuits by “vertical transistors” in which the differently doped regions are arranged one above the other or practically one above the other. Compared with the use of conventional transistors, the use of vertical transistors saves enough space to ensure an arrangement of a read/write circuit in the grid even with a reduced grid width.

  • Publication number: 20010030886
    Abstract: The magnetoresistive memory has a reduced current density in the bit lines and/or word lines. This avoids electromigration problems. The current density is reduced such that a compact field concentration is attained, for example, by the use of ferrite in the area around the magnetic memory cells.

  • Patent number: 6166565
    Abstract: The circuit arrangement has two electrical quantities in the form of a first quadrature-axis current component (I.sub.1) and of a second quadrature-axis current component (I.sub.2) that are compared to one another. The circuit arrangement has a first inverter unit (n.sub.1, p.sub.1) and a second inverter unit (n.sub.2, p.sub.2). Respectively one output (50, 52) of the two inverter units ((n.sub.1, p.sub.1, (n.sub.2, p.sub.2)) are coupled to an input of the respectively other inverter unit (52, 53). A reset unit (5) that initiates the comparison of the currents when activated is located between the two outputs of the two inverter units (n.sub.1, p.sub.2). When the reset unit (5) is deactivated, the output datum obtained in the evaluation remains stable.

    Abstract: The threshold value logic has a non-inverting circuit path (S) that and an inverting circuit path (S') are connected to at least one comparative weighting subcircuit (BC, BS). The non-inverting circuit path and the inverting circuit path preferably are of identical construction and each contain at least one neuron transistor (NT1, NT1').

  • Patent number: 6037885
    Abstract: A digital/analog converter has a neuron MOS transistor, a maintenance circuit which keeps the drain potential of the neuron MOS transistor constant, and a current source. A linear dynamic range in terms of large signal is possible, so that converters having a larger input word size than, for example, only two bits can be realized in a simple way with low dissipated power. Such converters are of significance particularly for ULSI circuits.

  • Patent number: 6037626
    Abstract: A semiconductor neuron has input electrodes are coupled capacitively to a floating gate (FG) whose potential controls the current of a MOS field effect transistor (NT). A respective neuron input (E1 . . . E4) can be connected to partial electrodes (1 . . . 7) of a respective input electrode in such a way that the total surface area of the partial electrodes connected to the respective neuron input corresponds to a respective weight of the neuron input. This results in high processing speed of a hardware neuron with the flexibility of a software neuron.

  • Patent number: 6028803
    Abstract: In the read amplifier a mismatch of the inception voltages of cross-coupled transistors (M5, M6) of the read amplifier are compensated by four further transistors (M1 . . . M4), whereby a defined equalizing of the bitlines advantageously takes place with these further transistors simultaneously in what is called the equalize phase. The compensation takes place in that the bitline that is connected with the transistor with the lower inception voltage is charged to a higher level in the pre-load phase. This higher bitline level is switched to the gate of the transistor connected with the other bitline. In the evaluation phase the transistor with the higher inception voltage becomes more strongly conductive. Read amplifiers of this sort are most significant for memory generations beginning at 1 Gbit, since the mismatch due to the variation of the input voltages of the transistors can no longer usefully be solved by a correspondingly large gate surface of the cross-coupled transistors in the read amplifier.

  • Patent number: 5990709
    Abstract: The circuit arrangement compares a quantity supplied by a first neuron MOS field effect transistor (M1) to a reference quantity that is made available by a reference source (R). A current mirror (SP) is provided therefor, this enabling a comparison of a second current (I.sub.2) supplied by a reference transistor (R) to a first current (I.sub.1) supplied by the first neuron MOS field effect transistor (M1). The evaluator circuit is activated or, respectively, decoupled by a first switch unit (S1) and a second switch unit (S2). What is thereby achieved is that no current flows in the evaluator circuit in the quiescent condition. The comparison result is applied to an inverter unit (IS). Since the inverter unit (IS) is decoupled from the evaluator circuit by the first switch unit (S1), an undefined level is never adjacent at the output (AIS) of the inverter unit (IS). This can be advantageously utilized in the further data processing in following stages.
