Semiconductor integrated circuit device and read start trigger signal generating method therefor

摘要

A semiconductor integrated circuit device includes a first memory cell array (100-0) corresponding to bank 0, a second memory cell array (100-1) corresponding to bank 1, first address transition signal generating circuits which detect transitions of input addresses (A0 - A20) and generate first address transition signals (ATD0 - ATD20), a second address transition signal generating circuit (11) which pre-detects an end of automatic execution of bank 0 or bank 1 and generates a second address transition signal (AUTOATD), and a read start trigger output circuit (12). The read start trigger output circuit (12) outputs a read start trigger signal (ALLATD) on the basis of the first address transition signals and the second address transition signal.
