A service searching system for searching a service in a distributed system comprises a wireless server device and a wireless terminal device. The wireless server device is connected to a network and implements a master search service. On the other hand, the wireless terminal device implements a slave search service, and is capable of communicating with the server by wireless and utilizing the master search service. Besides, the wireless terminal device comprises a storage means that caches service objects obtained through the master search service. In addition, in searching the slave search service for a service, the wireless terminal device begins by searching the service objects cached in the storage means. In the case where the service is not detected, the wireless terminal device searches the master search service. The service objects are cached by being related to priority data. Thereby, there is provided a service searching system comprising a wireless terminal device, which is intended to search for a service in a distributed system in which a range of services are distributed in a network, wherein it is possible to cut down a service-searching time and costs, and further, it is possible to cut down communication interruptions by noise etc. in the wireless communication section compared to the conventional one.

A cache device and a method for controlling cached data that enable efficient use of a storage area and improve the hit ratio are provided. When cache replacement is carried out in cache devices connected to each other through networks, data control is carried out so that data blocks set to a deletion pending status in each cache device, which includes lists regarding the data blocks set to a deletion pending status, in a cache group are different from those in other cache devices in the cache group.

To enhance the speed of first access (read access different in word line from the previous access) to a multi-bank memory, multi-bank memory macro structures are used. Data are held in a sense amplifier for every memory bank. When access is hit to the held data, data latched by the sense amplifier are output to thereby enhance the speed of first access to the memory macro structures.
