SEMICONDUCTOR MEMORY APPARATUS CAPABLE OF REDUCING THE WHOLE LAYOUT AREA OF A CIRCUIT

摘要

PURPOSE: A semiconductor memory apparatus is provided to reduce an access timing to a corresponding memory cell by suppressing the variation of the slew rate of a column selection signal.;CONSTITUTION: In a semiconductor memory apparatus, common column select signal transmission lines transmit a column select signal. The column select signal controls data access to a corresponding memory cell of a memory bank. Column select signal repeaters are insisted into the transmission line of the common column select signal transmission lines The column select signal repeater transmits the corresponding column select signal. The transmission path of the column select signal of the first memory bank is longer than that of the second memory bank.;COPYRIGHT KIPO 2011
