摘要：
A system and method for providing a programmable delay to an input signal in a device requiring setup and hold times for input signal, such as a DRAM device. In one embodiment, the programmable delay network 5 comprises a plurality of delay devices and at least one fuse connected between the input of the delay network 5 and the output of the delay network 5. Each fuse can connect in series with at least one delay device in such a manner that opening a fuse, or a combination of fuses, changes the amount of delay time the input signal experiences through the delay network.
