Synchronous burst-access memory and word-line driving circuit therefor

Abstract

A synchronous burst-access memory latches a row address strobe signal, a column address strobe signal, and address signals in synchronization with a clock signal. Data are stored in rows and columns in a memory cell array. Data in a selected row are input and output in serial bursts in synchronization with the clock signal, starting from a selected column. The row and initial column address are provided as external inputs; subsequent column addresses are generated by an internal address counting circuit. A word-line driving circuit for a synchronous memory uses transparent latches to latch the row address strobe signal and address signals, enabling row address decoding to be completed prior to synchronization with the clock signal.
