ABSTRACT:
The high speed readout circuit has an amplifier unit and an operating point setting unit and reads data from a memory sense line at high speed. The circuit further includes a unit for setting an operating point of the amplifier unit by short-circuiting the input and output terminals of the amplifier in response to a first control signal and precharging the sense line up to the operating point, and a unit for setting the sense line at a voltage slightly deviating the operating point in response to a second control signal by making use of a Miller capacitance and sensing the variations from the preset voltage during a reading process.
