Data access system, data access apparatus, data access integrated circuit, and data access method

摘要

When an LSI is connected to a plurality of memories that perform data transfers by a handshake access method, the need for the LSI to continuously output an access signal to a memory for a long period of time is eliminated. A hold circuit is provided between the LSI and the memory. The LSI outputs an access signal for specifying address information and a memory via a bus for a predetermined time period. The hold circuit holds the access signal and continually outputs the held access signal to the memory via a signal line connecting the hold circuit and the memory, in place of the LSI. After waiting until preparation for data transfer has been completed in the storage apparatus, the LSI again outputs an access signal and performs reading or writing of data.
