摘要

An internal memory section is divided into plural memory blocks. During a period of time, a relevant memory block of the internal memory section is connected to an external memory unit, while another memory block thereof is connected to a data holding section. During a succeeding period of time, the relevant memory block is connected to the data holding section, while the other memory block is connected to the external memory unit. Data exchange between the data holding section and the external memory unit via the internal memory section is performed while the alternative connection is repeated.
