Abstract: In a complex semiconductor device including embedded memories, the round trip latency may be determined during a memory self-test by applying a ping signal having the same latency as control and failure signals used during the self-test. The ping signal may be used for controlling an operation counter in order to obtain a reliable correspondence between the counter value and a memory operation causing a specified memory failure.

Abstract translation: 在包括嵌入式存储器的复杂半导体器件中，可以在存储器自检期间通过应用与在自检期间使用的控制和故障信号具有相同等待时间的ping信号来确定往返延迟。 ping信号可以用于控制操作计数器，以便获得计数器值与导致指定的存储器故障的存储器操作之间的可靠对应关系。
