Sense amplifier integrated circuit for high speed semiconductor memory, has current amplifier with input stage and output stage which are responsive to control signal that reduces gain of current amplifier

摘要

A current amplifier (110) has input and output stages electrically connected to the pair of differential input signal lines (IN,INB) and output signal lines (CSAO,CSAOB) respectively. The input stage and/or output stage are responsive to a control signal (XCON) that reduces a gain of the current amplifier, when the control signal is asserted. An independent claim is also included for output data amplifier of semiconductor device.
