Abstract: A semiconductor device and a method of verifying random number data capable of preventing erroneous judgement of data having periodicity as a random number and verifying randomness of random number data with high accuracy are provided. The semiconductor device includes a random number generator for generating random number data as serial data, and a health test circuit for verifying randomness of the random number data. The health test circuit handles the random number data as a data string of n-bit data by dividing the random number data by n bits (n is an integer larger than or equal to two). and verifies randomness based on the n-bit data.

Abstract: Information transmitted through wireless communications formed by information transmission lines from artificial satellites and radio towers or through wired communications established by cables is categorized into four categories. The individual information is transmitted in a broadcasting mode in synchronization with the information transmission timing defined for each individual information category. The information receiver captures and edits the received information and provides output for the service client in the manner associated with the individual category corresponding to the received information. Category-4 information is transmitted with the highest priority immediately when the information is generated; Category-3 information is transmitted periodically, for example, every five minutes; Category-2 information is transmitted at a time slot when the transmission line is relatively unoccupied; and Category-1 information is transmitted at a time slot when the transmission line is least occupied.

Abstract: A free page extracting unit extracts a free page of a non-volatile memory. A directory page writing unit writes, to the free page extracted by the free page extracting unit, a directory that includes a logical page/physical page translation table of a page to which updated data are to be written. Further, a data page writing unit writes updated data to the free page extracted by the free page extracting unit. Therefore, even when data updating operation is interrupted, loss of the original data can be prevented, and the data before updating can be recovered.

Abstract: In a non-contact IC card, corresponding to increase/decrease of an operation current of an internal circuitry, absorbing current of an ICC fluctuation absorbing circuit is temporarily decreased/increased by the amount corresponding to the increase/decrease, and thereafter, the absorbing current is gradually increased/decreased to the initial value and an output current of a regulator is gradually increased/decreased. Therefore, abrupt change in output current of the regulator can be prevented, and an internal power supply potential can be stabilized.
