摘要:
A semiconductor memory device of the invention includes: main decoders for generating wordline enable signals in response to first decoding signals, a first precharge signal, and a second precharge signal; wordline drivers for wordline drive signals in response to the wordline enable signals and second decoding signals; and a circuit for generating the second precharge signal in response to a command signal. The wordline drive signals are inactivated in sequence in response to the first decoding signals and the second precharge signal, in order to reducing ground noises.
