Abstract
A radio frequency identification (RFID) device includes an antenna configured to transmit or receive a radio frequency signal to or from an external communication apparatus; an analog block configured to generate a first power voltage in response to the radio frequency signal; a digital block configured to receive the first power voltage from the analog block, to transmit a response signal to the analog block, and to output a memory control signal; and a memory configured to read/write data in response to the memory control signal, the memory including a high voltage generating unit for generating a second power voltage from the first power voltage, a first portion driven by the second power voltage, and a second portion driven by the first power voltage, wherein the level of the first power voltage is lower than that of the second power voltage.
