摘要： The present invention relates to a method of programming a flash memory device. According to the present invention, after a program operation is completed, a program verify operation is repeatedly performed, wherein a threshold voltage of a programmed memory cell is also detected. If there are memory cells whose threshold voltage becomes low as a result of the detection, the program operation is again performed on a corresponding memory cell. It is thus possible to obtain a uniform distribution characteristic of a threshold voltage. Furthermore, a program verify operation is performed with a compare voltage being set higher than a target voltage initially so that a threshold voltage of a memory cell is sufficiently higher than the target voltage. The program verify operation is again performed while lowering the compare voltage according to the repetition number. It is thus possible to prevent normally programmed cells from being again excessively programmed.

摘要： Provided is a digital circuit for a passive RFID tag. The digital circuit for the passive RFID tag includes a construction that is divided into blocks, which receive a command, analyze and execute the command, and generate a reply signal respectively, according to the flow of data. Thus, the digital circuit transmits a clock signal to each of the blocks at a rate optimized for the block such that the blocks sequentially operate without any additional controller. The digital circuit for the RFID tag is constructed such that the respective blocks operate at different points in time. This precludes any useless operation of hardware, thus reducing the entire power dissipation.
