    摘要: A dynamic RAM semiconductor memory with a shared sense amplifier organization concept, in which the cell arrays are subdivided into blocks whose bit lines are connected in pairs from two adjacent blocks in each case to a common sense amplifier and the sense amplifiers are disposed between the cell blocks. In which case bit line switches are disposed in sense amplifier strips—lying between the blocks—between in each case two adjacent sense amplifiers in order to momentarily connect the other ends—not connected to the sense amplifiers—of two bit line pairs from the adjacent cell blocks during a precharge phase of a bit line pair activated directly beforehand. The precharge phase takes place at the start of a charge equalization phase.

    摘要: An integrated semiconductor memory includes at least one word line and a number of memory cells. Each memory cell has a selection transistor coupled to the word line. A word line driver is coupled to the word line. The word line driver provides a first electrical potential or a second electrical potential to the word line such that the word line is activated by the first electrical potential and is deactivated by the second electrical potential. A passive component (e.g., a diode or a resistor) is coupled between the word line and the second electrical potential such that the word line is coupled to the second electrical potential in a high-resistance fashion through the passive component. The passive component is transmissive for a leakage current between the word line and the contact connection.

    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 memory has individually addressable normal and redundant units of memory cells. A memory unit is used to store, in a normal mode, an address for one of the normal units which needs to be replaced by one of the redundant units. A comparison unit compares an address which is present on an address bus with an address stored in the memory unit and activates one of the redundant units in the event of a match being identified. The memory also has a test circuit which can be activated by a test mode signal, can reset the memory unit to an initial state, and can store an address for one of the redundant units in the memory unit for subsequently writing an identification code to this redundant unit.

    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 additional test mode is introduced in a semiconductor memory. A multiplicity of word lines are simultaneously activated by a word line decoder in the test mode. After a potential equalization of complementary bit lines, a logic “0” or a logic “1” is applied to an equalization circuit via a voltage generator. It is thus possible for the entire memory cell array to be preallocated an identical data value or, in strip form, alternating data values. Test time is thereby saved.

    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.

    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.
