    • In a parallel operational processing device having an operational processing unit arranged between memory blocks each having a plurality of memory cells arranged in rows and columns, the respective columns of each memory block are alternately connected to the operational processing units on the opposite sides of the memory block. By selecting one word line in one memory block, data can be transferred to two operational processing units. The number of the word lines selected per one operational processing unit is reduced, and power consumption is reduced. The bit operation units and sense amplifiers/write drivers of the operational processing units have arrangement pitch conditions mitigated and are reduced in number, and an isolation region between the memory blocks is not required and the layout area is reduced. Thus, the parallel operational processing device with a layout area and the power consumption reduced, can achieve a fast operation.
    • 在并行运算处理装置中,具有布置在各自具有排列成行和列的多个存储单元的存储块之间的运算处理单元,各存储块的各列交替地与存储器的相对侧的运算处理单元连接 块。 通过在一个存储器块中选择一个字线,可以将数据传输到两个操作处理单元。 每个操作处理单元选择的字线数减少,功耗降低。 操作处理单元的位操作单元和读出放大器/写驱动器具有减轻的布置节距条件,并且数量减少,并且不需要存储器块之间的隔离区域,并且布局面积减小。 因此,具有布局面积和功耗降低的并行运算处理装置可以实现快速运行。

    • A CAM (Content Addressable Memory) cell includes first and second data storage portions storing data, horizontal port write gates for storing data applied through a match line pair in the data storage portions in a data write through a horizontal port, and search/read gates for driving the match lines of the match line pair in accordance with the data stored in the data storage portions in a search operation and in a data read through the horizontal port. The match lines are used as horizontal bit line pair, or signal lines for accessing the horizontal port. As the first and second data storage portions are used, it becomes possible to store ternary data, and accordingly, a write mask function of inhibiting a data write at a destination of data transfer is realized. Further, as the CAM cell is used, an arithmetic/logic operation following a search process can be executed selectively, and high speed data writing/reading becomes possible.
    • CAM(内容可寻址存储器)单元包括存储数据的第一和第二数据存储部分,水平端口写入门,用于通过水平端口在数据存储部分中存储通过匹配线对应用的数据,以及搜索/读取门 用于根据搜索操作中存储在数据存储部分中的数据和通过水平端口读取的数据来驱动匹配线对的匹配线。 匹配线用作水平位线对或用于访问水平端口的信号线。 当使用第一和第二数据存储部分时,可以存储三进制数据,因此实现了在数据传送目的地禁止数据写入的写掩码功能。 此外,当使用CAM单元时,可以选择性地执行搜索处理之后的算术/逻辑运算,并且可以进行高速数据写入/读取。
