    • A stacked memory comprises one or more memory core chips and a fuse chip. Each of the memory core chips has a memory cell array including spare memory cells for replacing defective memory cells. The fuse chip has a fuse unit including a plurality of fuse elements whose electrical cut state corresponding to a replacement with the spare memory cells can be set. Also the fuse chip has a redundancy cell control circuit for controlling a redundancy cell operation of the defective memory cells based on state information of the fuse unit.
    • 堆叠存储器包括一个或多个存储器核心芯片和熔丝芯片。 每个存储核心芯片具有包括用于替换有缺陷的存储器单元的备用存储单元的存储单元阵列。 熔丝芯片具有包括多个熔丝元件的保险丝单元,其中可以设置与替换备用存储单元相对应的电切断状态。 熔丝芯片还具有冗余单元控制电路,用于基于保险丝单元的状态信息来控制有缺陷的存储器单元的冗余单元操作。

    • Disclosed are a memory command address system and a memory module that can be operated not only for 266 MHzCLK but also for 200 MHzCLK, in which clock timings in the input sections of a PLL, a register, and a DRAM are matched to one another, a DLL (delay locked loop) is provided in the register, the output timing of CA signal from the register is controlled so that the setup time margin and the hold time margin of the CA signal with respect to the clock signal with the additional latency in the DRAM=1.5 or 2.0 are equated to each other, such that clock operation of 266 MHz, for example, is made possible. If both 266 MHz and 200 MHz are used, by taking account of the timing budget, control is made for retarding the timing of the CA signal input to the flip-flop which receives an internal clock signal (intCLK) supplied to the flip-flop for determining the CA signal output timing from the register. Alternatively, control is made for switching between the replica (replical) provided in the register and an output unit associated with the replica, depending on the frequency being used, so as to cope with both frequencies simply by providing one sort of the module and one sort of the register.
    • 公开了一种存储器命令地址系统和存储器模块,其不仅可以用于266MHzCLK,而且可以用于200MHzCLK,其中PLL,寄存器和DRAM的输入部分中的时钟定时彼此匹配, 在寄存器中提供DLL(延迟锁定环),控制来自寄存器的CA信号的输出定时,使得CA信号的建立时间余量和保持时间裕度相对于时钟信号具有额外的等待时间 DRAM = 1.5或2.0彼此相等,使得例如266MHz的时钟操作成为可能。 如果使用266MHz和200MHz,通过考虑时序预算,进行控制以延迟输入到触发器的CA信号的定时,该触发器接收提供给触发器的内部时钟信号(intCLK) 用于确定来自寄存器的CA信号输出定时。 或者,根据所使用的频率,进行控制以在寄存器中提供的副本(复制)和与副本相关联的输出单元之间进行切换,从而简单地通过提供一种模块和一个模块来处理两个频率 排序的注册表。

    • A semiconductor device for testing highly integrated semiconductor devices in a compression mode by using a simple circuit and a specific physical pattern without using address data. The semiconductor device contains memory cell arrays and a device for selecting a test pattern input terminal which selects where a test pattern is to be input from among plural lines selected from bit lines and word lines, and a further device for generating a physical pattern which is constructed so that certain data is inputted in the lines selected to receive the test pattern, and so that the data is simultaneously outputted to data buses connected to plural lines other than the selected lines.
