DATA ACCESS SYSTEM, DATA ACCESS DEVICE, DATA ACCESS INTEGRATED CIRCUIT AND DATA ACCESSING METHOD

摘要

PROBLEM TO BE SOLVED: To avoid keeping outputting an access signal to a memory in which an address bus is a long time 1 when the memory executes data transfer in a handshake accessing method with an LSI connected to a plurality of memories.;SOLUTION: A hold circuit is provided between the LSI and the memories. The LSI outputs an access signal for specifying address information and a memory to a bus as long as a predetermined time. The hold circuit holds the access signal and continuously applies a signal line connecting the hold circuit and the memory with respect to the memory. The LSI selects a time when data transfer preparation is arranged in a storage device, outputs the same access signal again and executes data reading or writing.;COPYRIGHT: (C)2008,JPO&INPIT
