Abstract
A memory controller includes a command queue with multiple entry stacks, each with a plurality of entries holding memory access commands, one or more parameter indicators each holding a respective characteristic common to the plurality of entries, and a head indicator designating a current entry for arbitration. An arbiter has a single command input for each entry stack. A command queue loader circuit receives incoming memory access commands and loads entries of respective entry stacks with memory access commands having the respective characteristic of each of the one or more parameter indicators in common.
