    摘要: An integrated semiconductor memory device includes memory cells each with a selection transistor and a storage capacitor. Memory cells of this type are usually read by the potential of the bit line to which the memory cell is connected being compared in a sense amplifier with the potential of a complementary, second bit line and a voltage difference identified being amplified. The semiconductor memory according to the invention provides for that capacitor electrode which is not connected to the selection transistor to be connected to the complementary, second bit line. As a result, for an operating voltage with the same magnitude, larger quantities of charge can be stored in the storage capacitor since now the two mutually spread potentials output by the sense amplifier are used for biasing the storage capacitor. The resultant increase in the signal strength makes the semiconductor memory insensitive toward signal corruptions which arise for example in the case of operating voltages at different levels for selection transistors and for transistors in the signal amplifier.

    摘要: An integrated semiconductor memory device includes a memory cell array (B1) with a first bit line and a second bit line (BL, /BL), a controllable resistor (SW) and a control unit (100) configured to control the controllable resistor. In a first operating state of the integrated semiconductor memory device, the first and second bit lines are connected to one another via a first controllable switch (ET1) and also via the controllable resistor (SW) which has been set to a low resistance, to a connection (A10) that applies a mid-voltage (VBLEQ), where the voltage level of the mid-voltage is in the form of an arithmetic mean between a first and second voltage potential (VBLH, VBLL). By virtue of the control unit briefly setting the controllable resistor to a very low resistance in the first operating state of the integrated semiconductor memory device, the period of time required for the first and second bit lines require to assume the mid-voltage (VBLEQ) is shortened. The influence of capacitive coupling influences, which slow down the charging of the first and second bit lines to the mid-voltage, is significantly reduced as a result.

    摘要: An integrated circuit includes an input terminal (IN) for application of a supply voltage (Vext) and an output terminal (A) for generation of an output voltage (Vout). A first branch including a first controllable resistance (T1) and a second branch including a charge pump (10) and a second controllable resistance (T2) are connected between the input terminal (IN) and the output terminal (A). A control circuit (20) alters the resistance values of the first and second controllable resistances (T1, T2) in a manner dependent on a ratio of an actual value (Vout) of the output voltage to a desired value (VSout) of the output voltage and a ratio of an actual value (Vext) of the supply voltage to a desired value (VSext) of the supply voltage. As a result, the output voltage (Vout) can be stabilized to the desired value (VSout) virtually independently of fluctuations of the supply voltage.

    摘要: An integrated semiconductor memory includes a memory cell array with at least one memory cell, in which a data value is stored, and an evaluation circuit with a counter. During a test of the integrated semiconductor memory, a counter reading of the counter is altered if the data value stored in the memory cell deviates from a desired value. A threshold value is predefined by a control circuit. A programming circuit compares the threshold value on the input side with the instantaneous counter reading of the counter. If the counter reading of the counter exceeds the threshold value, a programming element changes from a first programming state to a second programming state. After the conclusion of the test, the state of the programming element is read out via an output terminal. This scheme makes it possible to deduce a possible cause of failure of the integrated semiconductor memory.

    摘要: An integrated semiconductor memory can be operated in a normal operating state synchronously with a control clock. In the test operating state, the integrated semiconductor memory is driven synchronously with a clock edge of the control clock with a first control signal and starts a test run independent of the control clock. Driving with the first control signal, selection transistors in a memory bank that can be selected by a memory bank address are turned off. Afterward, bit lines in the selected memory bank are interconnected and driven with a predetermined precharge potential. After a precharge time has elapsed, one of the word lines is selected by an applied word line address and the selection transistors in the selected memory bank connected to the selected word line are turned on. Precharge times are set and tested independently of the clock period of the control clock.

A device is provided for continuously comparing the acquired and stored amplitude value of the clock signal with an instantaneous amplitude value of the clock signal and for outputting a comparison signal which has a first logic state if the instantaneous amplitude value of the clock signal is less than the stored amplitude value and has a second logic state if the instantaneous amplitude value of the clock signal is greater than the stored amplitude value. A device is also provided for counting the number of logic states of the comparison signal which occur after the acquisition instant, and for signaling that the predetermined time value has elapsed if the counted number of logic states is equal to a predetermined number of logic states which corresponds temporally to the predetermined time value.
