摘要： A novel composite target material that is composed of a rare earth metal and a transition metal (iron-group metal) and which is used in the formation of a thin magnetooptical recording film by sputtering is disclosed. Also disclosed is a process for producing such composite target material.The process comprises the steps of providing a rare earth metal and an iron-group transition metal as separate entities, mixing these metals without alloying, and hot-forming the mixture at a temperature lower than the eutectic point of the system of metallic components in the mixture, thereby forming an intermetallic compound at the interface between the rare earth metal and the transition metal while causing said metals to be bonded together.The target material produced by this process contains 30-50 wt % of the rare earth metal, with the balance being made of the iron-group transition metal and incidental impurities. The structure of the target material is also characterized by the presence of an intermetallic compound phase at the interface between the particles of the rare earth metal and those of the transition metal. This composite target material has sufficiently high density, high strength, high deflective strength and good resistance to thermal shock to permit rotation and inversion during sputtering procedures without cracking. Furthermore, the oxygen content of this target material is no higher than 0.3 wt %. Therefore, a perpendicular magnetization film suitable for use in magnetooptical recording can be readily formed by sputtering the target material of the present invention. As a further advantage, the film deposition rate that can be achieved with this target material is significantly fast in comparison with the conventional alloy target material.

摘要： The semiconductor memory is facilitated with control circuitry for effecting plural self-refresh modes having respectively different refresh periods. The plural self-refresh modes are typified by a PS (pseudo) refresh mode which is applied when the memory is in the nonselected state for a comparatively long period of time, such as in the state in which memory backup is being facilitated, and by a VS (virtual) refresh mode in which the refreshing operation of the memory cells is effected intermittently during the intervals of memory accessings. The pseudo refresh mode has a longer refresh time period than the virtual refresh mode. The control circuitry also has counter circuits for the generating of refresh address signals in accordance with a first timing signal indicative of a pseudo refresh mode and a second timing signal indicative of a virtual refresh mode, the latter timing signal being a higher frequency signal. Such availability of plural self-refresh modes becomes particularly advantageous when considering consumption of the back-up power for maintaining the IC memory device versus stability of stored data. While the consumption of the back-up power for maintaining the device would be relatively lower under one of the self-refresh modes, namely, the PS (pseudo) refresh mode, the stability of data stored would, however, be greater under another self-refresh mode, namely, the VS (virtual) refresh mode.

摘要： A multiport memory is provided which permits both random access and serial access. In order to reduce parasitic capacitance and improve operating speed, the serial input/output lines are each divided into two parts at their middle points. Sense amplifiers for the serial input/output lines are provided at upper and lower ends of the serial access memory elements to respectively amplify signals from the divided lines. Additional features are provided for improving both the serial and random operation. For example, during the serial read mode, the column selector for random access is simultaneously operated, and read data passing through the random access column selector is used as head data for the serial output operation to be delivered through the serial output circuit. Also, a serial selector can be controlled by a select signal formed by a Gray Code counter to improve operating speed. Further features included a redundancy system for relief of defective bits, the use of common bit lines to improve integration density and an improved refreshing arrangement to reduce power consumption during the refresh mode.
