A security card 20 including a CPU 1 for executing instruction sequences such as a password verifying routine, a memory 2 configured to store secret data such as the password and so forth, a random signal generation circuit 4 configured to generate a wait signal which is output in order to halt the operation of the CPU 1. When the wait signal is input, the CPU 1 halts its operation for a short time such as one to several clocks. In accordance with the security card 20, the operation of the CPU 1 can be deferred for a short time in an arbitrary timing in order to make it difficult to analyze the operation of the CPU 1.

摘要:
A semiconductor circuit having a power supply voltage detection circuit to detect a potential level of an external power supply voltage and to output a detection signal depending on a comparison result with the potential level. A system control circuit detects the detection signal, outputs a status signal and an interrupt signal, and outputs a clock selection signal in response to an operation control signal. A CPU outputs the operation control signal to the system control circuit in response to the status signal and the interrupt signal. A clock generation circuit generates a plurality of clock signals and a clock selection circuit selects one clock signal among the plurality of clock signals in response to the clock selection signal. The clock selection circuit then outputs the one clock signal as a system clock signal.

A blood-purifying regenerated cellulose membrane, in which the occurrence of the leukopenia phenomenon and the activation of the complement system are moderated, is prepared by applying a solution of a polymeric substance comprising as one component units derived from one or more basic vinyl monomers having an amino group in the side chain in an organic solvent to a regenerated cellulose membrane, removing the excessive solution, and then fixing the polymeric substance to the regenerated cellulose membrane.
摘要:
A CPU and a memory are connected to each other through an address bus, a data bus, a read signal line and a write signal line. A read control signal and a write control signal transferred to the read signal line and the write signal line, respectively, are supplied to a control signal generating circuit. The control signal generating circuit detects a change in the read control signal and the write control signal transmitted to the read signal line and the write signal line, respectively, and then generates a control signal. The control signal generated by the control signal generating circuit is supplied to a pseudo-data generating circuit. The pseudo-data generating circuit generates pseudo-data comprising any random number data in accordance with the control signal and outputs the pseudo-data onto the data bus.
