Arrangement for switching a data reader amplifier on and off esp. for a semiconductor memory element with an additional switch for effecting a change in state of control signals

摘要

The apparatus includes a switch unit for connecting a reader amplifier unit to a bit line or a cell field region and for disconnecting the amplifier from the bit line or cell field region in dependence on the state of a control signal on a control line. The apparatus also has a driver to drive the control signal. An additional switch is provided which can cause a change in state of the control signal applied to the control line. Independent claims also cover a method of operating the apparatus.
