Abstract
A memory controller including a control unit for limiting the number of memory requests that are executed within a predetermined time period to regulate power consumption. The control unit may determine a memory request limit indicating the maximum number of memory requests that are allowed to be executed during the predetermined time period based on at least a carry-over limit and a new request limit. The carry-over limit may indicate the maximum number of carry-over memory requests that are allowed during the predetermined time period. The new request limit may indicate the maximum number of new memory requests that are allowed during the predetermined time period. The control unit may further control the number of memory requests that are executed in each of a sequence of predetermined time periods.
