Abstract
A semiconductor integrated circuit includes a first address transition detecting circuit which detects transitions of a row address signal and a column address signal of a memory cell array, a second address transition detecting circuit which detects only the transition of the column address signal, a control circuit which generates an internal circuit control signal with a desired period of time required for row access based on only a first detection signal and generates a column-related circuit control signal with a desired period of time required for column access to the memory cell array based on only a second detection signal, and a mode discriminator which determines one of the row access and the column access to be made and performs the access control operation based on the determination result.
