| 摘要 |
Control circuit for a data path of an S-DRAM which is clocked by a high-frequency clock signal, having a programmable mode register for storing a latency value; a latency generator for temporally delaying a data path control signal, generated by an internal sequence controller, with a switchable latency; a latency decoder, which switches the latency generator in a manner dependent on the latency value stored in the mode register, provision being made of at least one signal delay element, which can be switched in by the latency decoder and serves for the signal delay of the data path control signal with a specific delay time, the latency decoder switching in the associated signal delay element if the stored latency value is high.
