SEMICONDUCTOR DEVICE, ELECTRONIC COMPONENT, AND ELECTRONIC DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a semiconductor device that can keep a voltage on a transistor at a level equal to or lower than a predetermined value and can retain multilevel data.SOLUTION: In a configuration where electrical continuity between a source line SL precharged to potential VDM and a bit line BL is established through a transistor 11 to make the bit line discharge, at a data reading operation from a memory cell MC, for reading a potential retained at a gate of the transistor 11, the potential of the bit line BL is switched from VBL to GND in accordance with a drop in potential of the source line SL. The voltage between the source and drain of the transistor 11 can be kept at a level equal to or lower than a breakdown voltage by discharge.SELECTED DRAWING: Figure 3
