1. A semiconductor device comprising:
a memory cell array comprising a plurality of word lines, a plurality of bit lines each intersecting the word lines, and a plurality of memory cells each disposed at an associated one of intersections of the word and bit lines; and a row-based control circuit taking an active state, to access the memory cell array, and a standby state, to suspend accessing the memory cell array, the row-based control circuit being equipped with a current reduction circuit to reduce a power consumption during the standby state and configured to respond to a refresh command to take the active state at least twice with an intervention of the standby state therebetween, the row-based control circuit being further configured to activate two or more of the word lines each time the active state is being taken so that each of the memory cells coupled to the two or more of the word lines can be refreshed. |
