    摘要: An integrated semiconductor memory can include a plurality of subcircuit blocks arranged on nonoverlapping area sections. The subcircuit blocks each have a block supply line and a block ground line, which supply individual switching elements of the subcircuit blocks with a voltage. Each block supply line and block ground line is connected to a chip supply line and a chip ground line, which run outside the area sections of the subcircuit blocks. At least one connection between the chip supply line and the block supply line of at least one subcircuit block or between the chip ground line and the block ground line of at least one subcircuit block can be isolated by a switching device. Furthermore, a method for reducing leakage currents in a semiconductor memory, which, depending on the operating state of the semiconductor memory, isolates or connects individual subcircuit blocks of the semiconductor memory from or to a voltage supply.

    摘要: An electronic circuit for generating an output voltage has a defined temperature dependence, a bandgap circuit for generating a defined temperature-constant voltage and a temperature-dependent current with a defined temperature dependence, and a conversion circuit for generating the output voltage from the temperature-dependent current and the temperature-constant voltage. The conversion circuit has a first resistor at whose first terminal the temperature-constant voltage is applied, and whose second terminal is connected to a first terminal of a second resistor. The second terminal of the second resistor is connected to a supply voltage potential, and a first terminal of a third resistor is connected to the second terminal of the first resistor. The temperature-dependent current is supplied to a second terminal of the third resistor, and it being possible to tap the output voltage at the second terminal of the third resistor.

    摘要: A method and an integrated circuit for boosting a voltage are disclosed. A two-stage charge pump is used and has switches and capacitors. Known charges pumps can be single-stage or multi-stage and can achieve only a doubling of the input voltage in practice, depending on the configuration of the switches and capacitors and whereby each stage is provided with a separate drive. An improved two-stage charge pump can triple the input voltage and is advantageously achieved. N-type field effect transistors that are embedded in the substrate of an integrated circuit are utilized as the switches. It is further provided that a second series pass transistor is driven at its bulk terminal and/or its gate by a capacitor and a level shifter. This advantageously obviates the need to expand the width of the additional series pass transistor.

    摘要: An integrated circuit includes memory segments, each having at least one memory cell configurable in first and second states to store data, and a controller that controls programming and erasing of the memory segments. The controller maps external memory addresses of write data to internal memory addresses of erased memory segments with no memory cells in the first state such that erased memory segments are programmed with write data. When a write access occurs for an external memory address previously mapped to an internal memory address of a programmed memory segment with at least one memory cell in the first state, the controller remaps the external memory address to another internal memory address of an erased memory segment. The controller identifies programmed memory segments to be erased and controls selective erasure of the identified programmed memory segments, such as programmed memory segments no longer mapped to an external memory address.

    摘要: An integrated dynamic memory contains a control circuit for controlling a refresh mode in which the memory cells undergo refreshing of their contents. A controllable frequency generator serves for setting a refresh frequency. A temperature sensor circuit detects a temperature of the memory and outputs a first reference value, and an externally writable circuit is provided for outputting a second reference value. The temperature sensor circuit and the externally writable circuit are alternatively connectible to the control input of the frequency generator for setting the refresh frequency. If the externally writable circuit has been written, the second reference value, which corresponds to a temperature, is fed to the frequency generator; otherwise, the first reference value is supplied. In this manner, users of the memory that are unable to measure temperature can expediently optimize the power consumption that is necessary for standby mode and reduce it at low temperatures.
