Abstract
A static memory is constructed in a plurality of hierarchy levels. Beneficial realization possibilities are set forth with respect to the surface utilization for the drive and read-out circuits in the second hierarchy level which are especially critical. Memory cells that supply a strong cell signal are advantageously utilized so that a low expense is needed in the read circuit. By displacing periphery circuits into higher hierarchy levels, a short access time and a reduced surface requirement arise.
