Abstract
A control circuit supplies a word line drive voltage to one of m word lines which corresponds to a memory cell to which data is to be written, during a word line drive period including a first period and a second period following the first period, to decrease current capabilities of first and second load transistors included in the memory cell during the first period, and increase the current capabilities of the first and second load transistors during the second period.
