PURPOSE: A non-volatile semiconductor integrated circuit for controlling a sensed voltage is provided to drop a sensing voltage having a high voltage level by using a switching device and a coupling device. CONSTITUTION: In a non-volatile semiconductor integrated circuit for controlling a sensed voltage, a current sensing part(110) applies a certain current to a memory region(130). The current sensing part senses changed voltage which is varied according to the resistance state of a corresponding cell. A write driver(120) buffers input data. A memory region includes a plurality of PCRAM cells. A voltage controller(140) level-shifts a sensing voltage and outputs a sensing output voltage. A latch unit(150) latches a sensing output signal.
