Semiconductor memory device having electrically isolated memory and logic sections

摘要

According to this invention, there is disclosed a semiconductor device in which a memory section and a logic section are arranged on the same semiconductor chip, comprising a high-resistance element constituting a memory cell, a low-resistance line connected to the high-resistance element, a power source line serving as a power source path from a power source pad, a switching element arranged between the low-resistance line and the power source line, and a control circuit for controlling the switching element.
