摘要： A current mirror circuit has an input path, which has a current source and, connected in series therewith, a first transistor circuit with at least two transistors, wherein one of the transistors can be connected in parallel with the other of the transistors. In an output path, which has a second transistor circuit with at least two transistors, one of the transistors can be connected in parallel with the other of the transistors. The control terminals of the transistors of the first and second transistor circuits can be connected to the input path. As a result, the current mirror circuit can be changed over between two operating modes with a different current requirement with comparatively short changeover times.

摘要： An output circuit (OUT) can be activated via an activation input (AKT), in the activated state starts an output process for data (D) to be read out, in synchronism with the first internal clock (CLKI1), and outputs the data (D) with a specific phase shift (ΔTOUT) with respect to the first internal clock (CLKI1), in synchronism with the external clock (CLKE), at a data connection (P). A counting unit (CT) starts a counting process for recording the number of successively following first levels of the first internal clock (CLKI1) as soon as a second internal clock (CLKI2), which is synchronized to the external clock (CLKE), for the first time assumes a first level while an output control signal (PAR) is at first level. It activates the output circuit (OUT) as soon as the number of successively following first levels of the first internal clock (CLKI1) has reached a predetermined value.

摘要： A switching network with trimmable resistors lies in a control loop of a voltage generator that can be switched off from the supply voltage by a logic device. The logic device and also the switching network are driven by the same signals. The circuit configuration can be used for trimming or switching off the output voltage generated by the voltage generator during the functional test. As many settings as possible for the output voltage can be tested by a small number of control signals.

摘要： DDR SDRAM memory chips require a highly precise output clock signal in order to pass the stored data onto a data highway at the correct instant. This signal is generated by a symmetrical circuit configuration that, by virtue of the integration of a multiplexer in a clock ratio compensator, additionally generates the output clock signal in a minimal time.

摘要： A phase regulator is connected, on the input side, to the output of a phase comparator and generates a control signal in a manner dependent on the phase difference ascertained by said comparator. Updating of the control signal fed to a control input of a first delay unit is triggered by an edge of the first output clock signal occurring at the clock output of the first delay unit.

摘要： A synchronous semiconductor memory containing dynamic memory cells has a delay locked loop in order to synchronize a clock signal which actuates data output drivers with an externally supplied clock signal. An updating of the delay locked loop is suppressed during a Read state of the semiconductor memory. An appropriate control signal is produced by a state machine and is supplied to the delay locked loop. The synchronization of the data output with the supplied clock signal can be achieved in a precise manner and requires only simple circuitry.
