Publication number: 20200202959Abstract: A semiconductor memory device includes a differential waveform shaping circuit including first and waveform shaping circuits connected in parallel. The first waveform shaping circuit has a first inverting amplifier, and two inverters connected in series. The first inverting amplifier inverts and differentially amplifies an input signal having a rectangular waveform. Then, the output of the first inverting amplifier is passed through the two inverters. The second waveform shaping circuit has a first inverter, a second inverting amplifier, and a second inverter connected in series. The second inverting amplifier inverts and differentially amplifies the output signal from the first invertor, and the second inverter inverts the output signal from the second inverting amplifier. The differential waveform shaping circuit generates an output signal by averaging the output signal from the first waveform shaping circuit and the output signal from the second waveform shaping circuit.Type: ApplicationFiled: August 29, 2019Publication date: June 25, 2020Inventors: Kei SHIRAISHI, Masaru KOYANAGI, Mikihiko ITO, Yumi TAKADA, Yasuhiro HIRASHIMA, Satoshi INOUE, Kensuke YAMAMOTO, Shouichi OZAKI, Taichi WAKUI, Fumiya WATANABE
