Abstract
A semiconductor memory circuit which can operate with reduced value of peak currents. The memory circuit includes two or more memory cell arrays each having a plurality of memory cells and a peripheral circuit for achieving selective access operation is provided for each array. At least a timing signal and its delayed timing signals are generated in response to a control signal. Both of the timing signal and the delayed timing signal are used to enable the peripheral circuits at different timing.
