    • A semiconductor integrated circuit device includes a memory cell array for storing data to be processed, and an operational unit for effecting a predetermined operation on the data read from the memory cell array. The memory cell array has first and second regions for storing first and second data words of first and second groups. The first data words and second data words each include a plurality of data bits. The first region includes a plurality of bit arrays for storing data bits of the same digit in the first data words, and the second region includes a plurality of bit arrays for storing data bite of the same digit in the second data words. The bit arrays of the first and second groups are arranged alternately in the order of digits of the data words. The bit arrays storing the data bits of the same digit form one subarray. The data bits in one data word are stored in the same positions of the bit arrays. The operational unit includes operational circuits each corresponding to one of the subarrays. Each operational circuit effects the predetermined operation on the data read from the two bit arrays in the corresponding subarray. Each bit array has selectors responsive to external addresses to select one column from each bit array and connect this column to a corresponding operational circuit.

    • First-In First-Out (FIFO) memory device is disclosed. A ring pointer circuit sequentially and repeatedly selects memory cells in a memory cell array. When it is detected that a defective memory cell exists on a memory cell row, selection of that memory cell row is invalidated by the ring pointer circuit by cutting off a laser trimming line. In addition, by selectively cutting off laser trimming lines in a switching circuit and a redundancy ring pointer circuit, a redundancy memory cell row is selectively added in place of the defective memory cell row. Accordingly, stages required for the ring pointer circuit are maintained. In other words, the FIFO memory device having a defective memory cell is saved, resulting in improvement in yield in the manufacture.
    • 先进先出(FIFO)存储器件被公开。 环形指针电路依次重复地选择存储单元阵列中的存储单元。 当检测到存储单元行中存在有缺陷的存储单元时,通过切断激光修整线,通过环形指针电路对该存储单元行的选择无效。 此外,通过选择性地切断开关电路和冗余环形指针电路中的激光微调线,选择性地添加冗余存储单元行来代替有缺陷的存储单元行。 因此,保持环形指针电路所需的阶段。 换句话说,具有缺陷存储单元的FIFO存储器件被保存,从而提高了制造中的产量。

    • A serial access memory device is disclosed in which order of access to writing and reading memory cell columns can be controlled. A writing column selecting circuit and a reading column selecting circuit are each comprised of ring pointers with a controllable number of stages. The number of stages of the ring pointers is controlled in response to control signals stored in a serial interface circuit. As a result, two ring pointers each having two stages are formed in the writing column selecting circuit while one ring pointer having four stages is formed in the reading column selecting circuit. After two data signals are written in selected two memory cell columns in parallel, written data signals are read out from serially selected four memory cell columns at a speed twice that in the writing. This serial access memory device is applied to a progressive scan conversion circuit for video signal processing.
