Abstract
On one hand, a row address is provided via a buffer gate to a row address register,, and its output is provided via a complementary signal generation circuit,and a predecoder,to a word decoder,A. On the other hand, in response to an issuance of-an activate command a control signal AS,is provided via a delay circuit,to the clock input CK of the row address register,as a strobe signal AS,, and AS,is provided, to reduce timing margin, via a delay circuit,A to the strobe signal input of the predecoder,as a strobe signal S,. S,is provided via a delay circuit,B to the strobe signal input of the word decoder,A having RS flip-flops,to,or latch circuits. Each of the latch circuits consists of a NOR gate having a set input and a reset input and another NOR gate having an input coupled to receive the output of the former NOR gate and another set input to receive a multiple selection signal which is common for all the latch circuits in word decoders.
