Abstract
A computer system including a CPU and a memory subsystem connected via a system bus to communicate with each other, wherein the memory subsystem comprises a memory controller connected to the system bus, the computer system includes an up/down counter for counting a number of access requests and a number of requests other than access requests, a comparator for comparing the count of the up/down counter with a predetermined threshold value stored in a register, and a clock gate circuit for generating clock gate signals to decimate an operating clock of the memory controller in response to the comparison result of the comparator.
