    • A storage controller comprising a storage device adapter, a channel adapter, a cache memory, a control memory, and a plurality of buses connecting therebetween. The channel adapter communicates with a processor and processes input/output requests issued by the processor. The storage device adapter controls a storage device and data transfer between the storage device and the cache memory. The channel adapter and the storage device adapter exchanges control information via the control memory. The buses are used to transfer the data and the control information between the cache memory and the control memory, and the channel adapter and the storage device adapter. The controller also comprises bus load estimating means and bus mode selecting means. The bus load estimating means estimates bus load characteristics as an index based on the amount of data transfer during sequential access to the storage device. The bus mode selecting means determines a bus mode of bus utilization based on the index. Each of the channel adapter and the storage device adapter has bus access means for accessing the buses in accordance with the bus mode selected by the bus mode selecting means.
    • 存储控制器,包括存储设备适配器,信道适配器,高速缓冲存储器,控制存储器以及连接在它们之间的多个总线。 信道适配器与处理器通信并处理由处理器发出的输入/输出请求。 存储设备适配器控制存储设备和存储设备与高速缓冲存储器之间的数据传输。 通道适配器和存储设备适配器通过控制存储器交换控制信息。 总线用于将数据和控制信息传输到缓存存储器和控制存储器之间,以及通道适配器和存储设备适配器。 控制器还包括总线负载估计装置和总线模式选择装置。 总线负载估计装置基于在顺序访问存储设备期间的数据传输量来估计总线负载特性作为索引。 总线模式选择装置根据该索引确定总线利用的总线模式。 每个通道适配器和存储设备适配器具有总线访问装置,用于根据由总线模式选择装置选择的总线模式访问总线。

    • A digital signal recording and playback apparatus having a rotary heads mounted on a rotary drum capable of recording/reproducing a digital signal onto/from a magnetic tape at a tape speed which is N times as much as the standard speed while conforming to the standard track angle and length. The number of the rotary heads are increased from the standard two heads whereas the drum speed is made one half of N times standard speed and the drum diameter is made slightly larger from the standard so that the relative speed between the running tape and the rotating heads becomes equal to the standard in the double tape speed mode, and becomes twice that in the quadruple tape speed mode. Alternatively, the tape is wound around the drum having two heads, over the angular range of 180 degrees instead of the standard 90 degrees, the drum diameter is made smaller than the standard, and the drum speed is N times the standard so that the relative speed of the heads becomes equal to the standard in the double tape speed mode.

    • A stacked static random access memory SRAM having a plurality of memory cells is disclosed. Individual memory cell has a portion formed in an upper active element layer in the device structure and a portion formed in a lower active element layer in the device structure separated from the upper layer by an intermediate insulating layer. A word line, a bit line and access transistors are formed in the same upper active element layer, eliminating the need for interconnecting them through the insulating layer. The elimination of the inter-layer connections helps to reduce the number of through-holes required to be made in the insulating layer. This in turn reduces the area to be occupied by the memory cell and leads to a simplified manufacturing process of the SRAM.
    • 公开了一种具有多个存储单元的堆叠静态随机存取存储器SRAM。 单个存储单元具有形成在器件结构中的上有源元件层中的部分,以及通过中间绝缘层与器件结构中的下有源元件层中形成的部分形成在上层中的部分。 在相同的上部有源元件层中形成字线,位线和存取晶体管,消除了通过绝缘层将它们互连的需要。 层间连接的消除有助于减少在绝缘层中制造的通孔的数量。 这又减少了由存储器单元占用的面积,并导致了SRAM的简化制造过程。
