    摘要: An integrated semiconductor memory including memory cells which can be driven via first and second word lines and can be replaced by redundant memory cells. In the first memory cell type, data can be stored corresponding to the data present at a data input terminal. In the memory cells of a second memory cell type, data can be stored inverted with respect to data present at the data input terminal. The integrated semiconductor memory includes a circuit for data inversion, wherein the data are written to a redundant memory cell, inverted with respect to the data present at the data input terminal if the defective memory cell and the redundant memory cell replacing it are situated in different word line strips of a bit line twist, and if the defective memory cell and the redundant memory cell replacing it are associated with different memory cell types.

    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 dynamic memory includes memory cells which are combined to form individual independently addressable units, and a control circuit for controlling a refresh mode for the memory cells. The memory cells can have their memory cell content refreshed. The control circuit is designed such that one or more units of memory cells can be subject to a refresh mode in parallel in a refresh cycle. The control circuit sets a number of memory cell units, which are to be refreshed in parallel in a refresh cycle based on a temperature reference value. A maximum possible operating temperature for a memory chip can be increased without additional restrictions on memory access.

    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.
