A power-on reset circuit in an RFID(Radio Frequency IDentification) with a non-volatile ferroelectric memory is provided to generate a reset signal stably regardless of power-up slope by having delay time for system stabilization after a power-on reset sensing voltage arrives in the power-on reset circuit of the RFID. A pull-up current source(151) supplies a pull-up current. A ferroelectric capacitor part is connected between the pull-up current source and a ground voltage stage. A driver outputs a reset signal by being connected to a connection node of the pull-up current source and the ferroelectric capacitor part. A pull-up device supplies a pull-up voltage to the driver according to the output of one end of the driver. The ferroelectric capacitor part includes a plurality of ferroelectric capacitors connected between the pull-up current source and the ground voltage stage in parallel.
