Abstract
A circuit generates a boosted voltage in a semiconductor memory device, where the semiconductor memory device includes a memory cell array having a plurality of non-edge sub-arrays and at least one edge sub-array. The circuit includes a plurality of boosted voltage generators configured to generate a boosted voltage having different current driving capabilities to activate the non-edge sub-arrays and the edge sub-arrays and to supply the boosted voltage to the memory cell array.
