    • PURPOSE: A semiconductor memory device for high speed data access with improved refresh operation is provided to perform a stable operation by minimizing a refresh operation time. CONSTITUTION: A cell block(500) comprises (N+1) unit cell blocks by further including an additional unit cell block to have additional M word lines, with N unit cell blocks each having M word lines to correspond to an inputted row address. A spare cell block table(470) stores information as to whether to allocate at least one word line as a spare word line, among M word lines. A tag block(460) senses a logic cell block address to select N unit cell blocks by receiving the row address, and converts it to a physical cell block address to select one of the unit cell blocks, and stores the physical cell block address when the physical cell block address is converted. And a control unit(420) controls the tag block and the spare cell block table to enable one word line in the selected unit cell block and a spare word line set by information provided from the spare cell block table.
    • 目的:提供用于具有改进的刷新操作的高速数据访问的半导体存储器件,以通过最小化刷新操作时间来执行稳定操作。 构成:通过进一步包括具有附加M字线的附加单元单元块,单元块(500)包括(N + 1)单元单元块,每个具有M个字线的N个单元单元块对应于输入的行地址。 在M个字线中,备用单元块表(470)存储关于是否分配至少一个字线作为备用字线的信息。 标签块(460)通过接收行地址来检测逻辑单元块地址以选择N个单元单元块,并将其转换为物理单元块地址以选择单元单元块中的一个,并存储物理单元块地址 物理单元块地址被转换。 并且控制单元(420)控制标签块和备用单元块表以使得所选单元单元块中的一个字线和由备用单元块表提供的信息设置的备用字线。

    • PURPOSE: A semiconductor memory device and its control method are provided to achieve efficiency and high speed of refresh control and to interface-exchanged with a high speed SRAM. CONSTITUTION: According to a cell array having a plurality of memory cells, one memory cell has the first and the second memory cell transistor(Tr1,Tr2) connected serially between a write bit line and a read bit line. A capacitor(C) for data accumulation is connected to a contact point of the first and the second memory cell transistor, and another end of the capacitor is connected to a ground potential. Gate ports of the first and the second memory cell transistor are connected to a write word line and a read word line respectively. The first word line is connected to a word driver of the first X decoder((WF)111W) decoding a row address or a refresh address of a write address, and the second word line is connected to a word driver of the second X decoder((RF)111R) decoding a row address or a refresh address of a read address.
