SEMICONDUCTOR MEMORY APPARATUS AND DATA BUS AMPLIFIER ACTIVATING METHOD OF THEM

PURPOSE: The semiconductor memory apparatus provided generation timing has a few margin of a data bus amplifier enable signal for activating a data bus amplifier mounted against a data bus. CONSTITUTION: The semiconductor memory apparatus comprises: a memory cell array, a column selection circuit, an extraction data bus, and record data bus. The column selection circuit select column of the memory cell array. The extraction data bus transmit extraction data generated by the column selected the column selection circuit select to the extraction data bus. The record data bus transmit record data generated by a data bus amplifier to the column selected the column selection circuit. COPYRIGHT 2000 KIPO ...
