Semiconductor integration circuit device |
摘要 |
A semiconductor integrated circuit device includes a first variable delay circuit which delays a timing signal for activating a sense amplifier which is supplied with a signal read out from a memory array and amplifies the signal so that a timing difference between a dummy signal read out from a dummy memory cell and the timing signal of the sense amplifier is detected by a detection circuit to be made small in accordance with an output of the detection circuit, and a second variable delay circuit which adjusts a relative timing difference between the dummy signal and the timing signal of the sense amplifier.
