Abstract

There is provided memory control device and memory control method, which can prevent wiring complication by many crossing wirings, and reduction of yield and quality. When a memory control device CC1 selects a memory chip CC2, an internal circuit of a select circuit 27 is changed by a switch signal SWS2. In this case, the changeover is made so that a select signal S2 outputted from an internal circuit 40 is inputted to a predetermined memory terminal of the memory chip CC2. The select signal S2 is inputted to the corresponding predetermined memory terminal of the memory chip CC2, and thereby, the memory chip CC2 is activated, and set to a state capable of inputting and outputting control signals 21 to 25. The control signals 21 to 25 are assigned to control terminals P21 to P27 after being hanged by the select circuit 27 in signal sequence corresponding to terminal array sequence of memory terminals 21a to 27a of the memory chip CC2.
