Title: Cache memory testing method
Inventor: NARITA YOSHITAKA
IPC: G06F12/08
Filed: 1989-09-28
Abstract: PURPOSE:To conduct a test on an instruction cache memory only by means of adding a test mode signal to an instruction decoder by checking the built-in instruction cache memory at the external part of a micro processor. CONSTITUTION:When a signal 104 comes to '1' and is inputted, the instruction decoder 10 continuously outputs '0' even if the instruction code of a signal 105 comes to any value. A content which is read from the instruction cache memory 6 is inputted to a computing element 17, which outputs data as it is and sets it in a register 18. Then, a program sequencer 12 generates a subsequent address, sequentially reads the instruction cache memory 6 and outputs it to a data address bus 102, namely, the external part of the micro processor. Thus, the test of the instruction cache memory 6 is conducted only by adding the test mode signal for instruction decoding and without adding hardware for the test and without cache access being delayed.

Title: Magnetic semiconductor device and actuator using it
Inventor: NAKAMURA OSAMU
IPC: B81B5/00
Filed: 1993-09-20
Abstract: PURPOSE:To shift the state of a magnetic semiconductor layer between a ferromagnetic state and paramagnetic state by controlling the formation of magnetic polarons by impressing an electric field upon the magnetic semiconductor layer. CONSTITUTION:When a negative voltage is applied across a metallic electrode 3, the Fermi level of a magnetic semiconductor layer 1 becomes a variable energy level and, in the layer 1, the level changes downward in accordance with the magnitude of the applied voltage. As a result, the electrons existing at the donor level of the layer l below an insulating film 2 are discharged to a conduction land and only ionized donors exist at the donor level of the layer 1. Therefore, local magnetic polarons formed in the layer 1 disappear and the direction of a local magnetic moment at the part becomes random and the part changes from a ferromagnetic state to a paramagnetic state. The area which becomes the paramagnetic state in the layer 1 increases in the of direction of the depth as the absolute value of the negative voltage applied across the electrode 3 becomes larger.
