摘要： Disclosed herein is a measurement apparatus for improving performances of standard cells in a standard cell library when verifying performance of the standard cell library through a ring oscillator among various test element groups (TEGs). A built-in circuit is used to measure and verify performance of the standard cell library through a TEG. Therefore, it is possible to effectively improve performances of the standard cells in the standard cell library. Particularly, it is possible to not only remove human errors or internal errors of equipment, but also perform the measurement more readily, rapidly and accurately. Further, it is possible to curtail the use of high-performance equipment or manpower and time required in a measurement process.

摘要： A radio frequency identification reader and a radio frequency identification tag that use an ultrahigh frequency band, and action methods of the radio frequency identification reader and the radio frequency identification tag. The radio frequency identification reader includes: a data generator generating data to be transmitted to a radio frequency identification tag; if a command to control the radio frequency identification tag has to be authenticated, a reader controller controlling the data generator to generate the data including an authentication code; and a reader transmitter transmitting the data to the radio frequency identification tag. As a result, securing of communications of a specific command between the radio frequency identification reader and the radio frequency identification tag can be reinforced.

摘要： Disclosed herein is a measurement apparatus for improving performances of standard cells in a standard cell library when verifying performance of the standard cell library through a ring oscillator among various test element groups (TEGs). The measurement apparatus includes a ring oscillator block activated in response to an enable signal externally inputted thereto for outputting measurement result values, a decoder for selectively outputting one or more of the measurement result values from the ring oscillator block, and a statistics assistor for receiving output values from the decoder for a predetermined period and outputting a maximum value, a minimum value and an average value of the received values. The ring oscillator block includes a pulse generator for generating a pulse in response to the enable signal, a pulse stable unit for synchronizing the pulse generated by the pulse generator with a system clock pulse, a clock enable unit for outputting the system clock pulse according to a state of the pulse outputted from the pulse stable unit, a counter operating at any one of a rising edge and falling edge of the system clock pulse outputted from the clock enable unit, and a captured data storage unit responsive to the enable signal for receiving an output of the counter and storing a final count value or outputting it to the decoder.
