Original Abstract Submitted
a semiconductor device includes memory cells connected to word lines, bit lines, and one source line, a row decoder connected to the word lines, and a sense amplifier circuit connected to the bit lines. in a program operation for two or more selected memory cells, a reference voltage is applied to the one source line, the sense amplifier circuit inputs a selected voltage to one selected bit line connected to the selected memory cells, and the row decoder inputs, to selected word lines connected to respective ones of the selected memory cells, a first program voltage lower than the reference voltage or a second program voltage higher than the reference voltage. each of the memory cells includes a ferroelectric layer in which at least one of a polarization direction and a polarization degree changes depending on a voltage input to each of the word lines.
