DATA INPUT/OUTPUT LINE SENSING CIRCUIT OF SEMICONDUCTOR INTEGRATE

摘要

The circuit comprises a differential amplifier connected to one pair of differential data input/output lines and having first and second differential amplifier output lines. The differential amplifier amplifying the data read from a memory cell provides the amplified data to the first and second. differential amplifier output lines in response to an activation state of a sensing control signal. A precharge circuit is incorporated to precharge the first and second differential amplifier output lines of the differential amplifier to a set precharge voltage level in response to a non-activation state of the sensing control signal. A latch sense circuit has first not-enabled state and second enable-activated state. The latch sense circuit comprises first and second input nodes connected respectively to the first and second differential amplifier output lines.
