Abstract

All memory commands are classified into two categories: background commands and foreground commands, depending on whether they are data related or not. The pointed background command and foreground commands are issued onto the DRAM bus at the earliest time when the required constrains are met. The background and foreground FSM controllers work in a pipelined or overlapped manner.
