RFID DEVICE HAVING A MEMORY FOR CORRECTING A FAIL CELL AND METHOD FOR CORRECTING A FAIL CELL THEREOF

摘要

An RFID device including a memory capable of correcting defective cell and a correction method thereof are provided to improve yield of the RFID device by correcting cell data distributed in the memory at random by comparing data of unit cells of each group. An analog block(20) transmits/receives data from an external communication device and analyzes the data. A digital block(30) receives and processes a power supply voltage and a signal for data transmission from the analog block, and transmits a response signal to the analog block and outputs a memory control signal. A memory(40) is controlled by the memory control signal and stores same data in each memory group in a write mode by separating a constant number of unit cells into one memory group and then judges same data as effective data by comparing cell data of the memory group selected in a read mode.
