    • A semiconductor memory device and method for its test is disclosed including a CBR (CAS before RAS) refresh test achieved by inputting a CBR command for every redundant word line to be selected. In this way, redundant word lines may be selected without repetition until all of the redundant word lines have been selected. By doing so, an accurate determination of the refresh period may be obtained. A CBR refresh counter (15) may be activated every time a control signal is received when a refresh test on redundant memory cells (RC) is performed. Redundant counter signals (RCNT0 to RCNT5) may be applied to a X address buffer (2A). X address buffer (2A) may select the redundant counter signals (RCNT0 to RCNT5) to sequentially select the redundant word lines (RWL0 to RWL63) when a redundant refresh test is performed.
    • 公开了一种半导体存储器件及其测试方法,包括通过为将要选择的每个冗余字线输入CBR命令而实现的CBR(RAS之前的CAS)刷新测试。 这样,直到所有的冗余字线都被选中,冗余字线才可以被选择而不重复。 通过这样做,可以获得刷新周期的准确确定。 每当执行冗余存储单元(RC)的刷新测试时接收到控制信号时,CBR刷新计数器(15)可以被激活。 冗余计数器信号(RCNT0至RCNT5)可以应用于X地址缓冲区(2A)。 当进行冗余刷新测试时,X地址缓冲器(2A)可以选择冗余计数器信号(RCNT0至RCNT5)以顺序地选择冗余字线(RWL0至RWL63)。
