STORAGE DEVICE, INTERNAL CONTROL METHOD FOR STORAGE DEVICE, SYSTEM, AND CONTROL METHOD FOR STORAGE MEANS IN SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a storage device to which efficient access can be performed and in which current consumption can be reduced without changing a package, an internal control method for a storage device, a system, and a control method for a storage means in a system. SOLUTION: A memory device changes a shape of a logic address map of a DRAM core in accordance with a page length specifying signal outputted from a mode register. And when page length is set shorter than full page by the page length specifying signal, a row address Row increased by the above is taken in simultaneously with a column address Co1 at the time of the first red-command RD1. At the time, the address Row being increased is taken in from an external address terminal being not used at the time.
