Abstract
A passive wireless memory device includes a memory unit and a passive tag. The passive tag converts data stored in the memory unit into a data packet in response to first to third data request signals from a reader and transmits the data packet to the reader. The passive tag determines the size of the data packet in response to the channel state predicting flag and the second and third data request signals.
