Sense amplifier for high speed sensing, memory apparatus and system including the same

摘要

A sense amplifier includes a current supply unit, an amplification unit, a pass transistor and a latch unit. The current supply unit may be configured to provide a sensing current to a sensing node. The amplification unit may be configured to amplify a voltage difference between the read reference voltage with the voltage level of the global bit line. The pass transistor may be configured to transfer a current from the sensing node to the global bit line based on a signal output from the amplification unit. The latch unit may be configured to generate an output signal by detecting a voltage level change of the sensing node.
