A SEMICONDUCTOR MEMORY DEVICE WITH FAST INPUT/OUTPUT LINE PRECHARGE SCHEME AND A METHOD OF PRECHARGING INPUT/OUTPUT LINES THEREOF

摘要

This semiconductor memory device of the present invention disclosed in the interrupt detector includes writing the precharge signal generator, and a precharge circuit. The write interrupt detector is information for notifying the during normal mode write interrupt and occurs whether to detect a write interrupt detection signal fingers doeeotneun applied from outside, the precharge signal generator in response to said write interrupt detection signal when the normal mode, the and generating first and second pre-charge signal. Finally, the precharge circuit of the read / write prior to the normal mode when the write interrupt the first and second response to the precharge signal are arranged in an array on both sides of the memory cell, the first and second output line pairs free accounts. According to this structure, when the normal mode can be reduced, the write time and the address access time of the semiconductor memory device, and as a result it is easy to implement a high-speed semiconductor memory device.
