PURPOSE:To shorten access time by shortening the time until a one-shot signal reaches an equalization potential level by holding a transistor, used for equalization, at a potential low enough not to turn on. CONSTITUTION:An address input signal ADi is inputted and its complementary signals AD'i and A'Di' are generated by an address buffer circuit AB; and they are inputted to NOR circuits N2 and N1 directly and through delay circuits 21 and 20 respectively, and the outputs of the gates N1 and N2 are supplied to an NOR gate N3 to obtain a one-shot signal Ai'. Similarly, one-shot signals are detected with regard to other addresses AD1-AD12 by setting an OR gate RG, obtaining a signal EQ. |
