A method for operating an integrated memory unit having a memory cell field includes
the steps of, before a memory access, partitioning the memory cell field into a
plurality of memory areas, for memory access, selecting one of the memory areas
through the application of a memory area address, during the memory access, and
internally generating addresses for access to memory cells of the one of the memory
areas by the memory unit. Through a common external terminal connection of the
memory unit, the memory area addresses are transmitted, and, subsequently, access
data of the one of the memory areas are transmitted successively. The operating
method enables a comparatively low number of terminal tendons.
