摘要

The semiconductor memory element has multiple inlet or outlet ports for entering command signals for a mode revitalization operation, and a memory field (190), which has a divided storage area that is accessible over multiple inlet or outlet ports. The memory field is divided into different storage areas. A distribution control block (300) assigns a right of access in reaction to an external command signal, where the distribution control block produces distribution control signals. Independent claims are also included for the following: (1) a method for assigning a right of access, which involves assigning a right of access, over a divided storage area (2) a method for refreshing storage areas in a semiconductor memory element, which involves refreshing two storage area in two mode.
