Abstract
In an integrated semiconductor memory having a memory cell array divided into memory banks, supply potentials with high drive capability are applied to the memory banks only if the respective memory bank is activated for access to a memory cell. For this purpose a supply voltage assigned to the respective memory bank is controlled by the same address signal as the memory bank. The supply voltage sources generate a word line potential, a bit line potential or a substrate potential. As a result, a power loss is reduced.
