    • An external terminal receives an external signal so as to access the first and second memory chips. The test starting terminal receives a test starting signal activated when the first or second memory chip is tested and inactivated when the first and second memory chips are normally operated. The access signal generator converts the external signal to a memory access signal of the first memory chip. The first selector selects the external signal, which is a test signal, during activation of the test starting signal, selects the memory access signal during the inactivation of the test starting signal. That is, during the test modes, the first memory chip can be directly accessed from the exterior. For this reason, the test program for testing the first memory chip alone can be diverted as the test program following an assembly of the semiconductor device.
    • 外部终端接收外部信号以访问第一和第二存储器芯片。 当第一和第二存储器芯片正常工作时,测试启动终端接收到测试启动信号,当第一或第二存储器芯片被测试和非激活时激活。 访问信号发生器将外部信号转换为第一存储器芯片的存储器访问信号。 第一选择器在激活测试启动信号期间选择作为测试信号的外部信号,在测试启动信号失效期间选择存储器访问信号。 也就是说,在测试模式期间,可以从外部直接访问第一存储器芯片。 因此,在半导体器件的组装之后,用于单独测试第一存储器芯片的测试程序可以作为测试程序转移。
