Abstract: PURPOSE: A power up reset circuit of a memory chip is provided to prevent the error operation of the memory chip by generating a stable power up reset signal regardless of an external environment. CONSTITUTION: When a power is turned on, a transistor(P8) is turned on by the voltage of the second node, and the voltage of the first node follows up a level of a source voltage(Vcc). And, because transistors of the second transistor chain(112) are turned off, the power supply of a charge to the second node is intercepted. For this reason, a voltage of the second node reaches to a ground voltage by the third transistor chain(113). Finally, because the voltage of the second node outputs a high level(RESET) through inverters(I4 to I6), the second node generates a power up reset signal.
