Title: Memory control system
Inventor: USUI MINORU
IPC: G06F1/32
Filed: 2001-05-31
Abstract: PROBLEM TO BE SOLVED: To put a system into sleep state without complicated software processing in the memory control system having an interface of volatile semiconductor memory. SOLUTION: A processor, when it fetches a sleep command, halts its own operation and outputs an internal power down signal. A power down control circuit, when it receives the internal power down signal from the processor, outputs a control signal for shifting the volatile semiconductor memory connected to a system bus to a self refresh mode. Thereby, only if the processor fetches the sleep command, the semiconductor memory can be shifted into the self refresh mode. Because it is unnecessary to write a processing program for shifting the semiconductor memory to the self refresh mode in a program, the software processing is prevented from becoming complicated. Accordingly, the burden on a program developer can be reduced.
