发明名称 Semiconductor memory device suitable for mounting on portable terminal
摘要 A trigger producing circuit provides a trigger signal. A delay circuit receives the trigger signal, and provides a delay signal produced by delaying the trigger signal. A clock counter receives clocks, counts the received clocks for a period from reception of the trigger signal to reception of the delay signal, and provides a result of the counting. A determining circuit stores a relationship between the number of clocks and a latency, and determines the latency corresponding to the result of counting provided from the clock counter. A latency register holds the determined latency. A WAIT control circuit externally provides a WAIT signal based on the latency held in the latency register.
