The present invention relates to a semiconductor memory device to execute a refresh operation in such a manner that an entry and an exit of a self refresh mode is carried out. The input signal is divided into two, first and second, data streams. The memory includes one or more instructions executable by the processor to enable the users of the system to rate each other based on at least one of sharing, exchanging, and selling one of activity, service or product. Functional calls to a sequence of SIBBs along with customer specific data stored in a database comprise a complete customer application.
