半导体存储装置
摘要：
本发明公开了一种能够执行第一模式和第二模式的半导体存储装置，所述第一模式具有第一潜伏期，所述第二模式具有比所示第一潜伏期长的第二潜伏期。该半导体存储装置包括：焊盘单元，该焊盘单元被配置为从外部接收地址和命令；第一延迟电路，该第一延迟电路被配置为将所述地址延迟与所述第一潜伏期对应的时间；第二延迟电路，该第二延迟电路包括串联的移位寄存器，并被配置为将所述地址延迟与所述第一潜伏期和所述第二潜伏期之间的差值对应的时间；以及控制器，该控制器被配置为在执行所述第二模式时使用所述第一延迟电路和所述第二延迟电路。
摘要（英）：

The invention discloses a semiconductor memory device which is capable of executing a first mode having a first latency and a second mode having a second latency longer than the first latency. The semiconductor memory device includes: a pad unit configured to receive an address and a command from the outside; a first delay circuit configured to delay the address by a time corresponding to the first latency; a second delay circuit including shift registers connected in series and configured to delay the address by a time corresponding to a difference between the first latency and the second latency; and a controller configured to use the first delay circuit and the second delay circuit when executing the second mode.
