摘要: For each of pads for control clock signals and address signals included in a DRAM, an n type well region is provided, and each n type well region is connected to an upper power supply means only by means of a first lower power supply line. Therefore, compared with the conventional device in which n type wells are connected to each other by a second lower power supply line, current flowing from the resistance element in a p type well to the upper power supply line is reduced. Therefore, damage to the resistance element 8 can be prevented, and surge immunity of the DRAM is increased.
摘要翻译: 对于包括在DRAM中的控制时钟信号和地址信号的每个焊盘,提供n型阱区,并且每个n型阱区仅通过第一较低电源线连接到上电源装置。 因此,与通过第二低电源线连接n个型阱的常规装置相比,减小了从p型阱中的电阻元件流向上部电源线的电流。 因此,可以防止对电阻元件8的损坏,并且DRAM的浪涌抗扰度增加。
