Abstract
A semiconductor memory device has a hierarchical or divided wordline structure wordline structure. Sub-wordline activation signals are arranged such that the number of sub-wordline drive units in memory blocks to which one sub-wordline activation signal is supplied is identical to that of sub-wordline drive units in memory blocks to which the other sub-wordline activation signal is supplied. Upon such sub-wordline activation signal arrangement, power consumption is not imbalanced when each of the sub-wordline activation signals has high level of a boosting voltage.
