Sense amplifier and semiconductor memory device using it

A sense amplifier having a pre-amplifier and a main-amplifier is disclosed. The pre-amplifier is connected to paired data line, senses and amplifies data on the paired data line using voltage mode and outputting a pair of differential signal. The main-amplifier is connected to the paired data line,...

More Information
Summary:A sense amplifier having a pre-amplifier and a main-amplifier is disclosed. The pre-amplifier is connected to paired data line, senses and amplifies data on the paired data line using voltage mode and outputting a pair of differential signal. The main-amplifier is connected to the paired data line, senses and amplifies data on the paired data line using current mode and generating a first amplified signal, senses and amplifies the first amplified signal using voltage mode in response to the pair of differential signal, and outputting an amplified data.
