Abstract

A method and a related DRAM controller for refreshing a DRAM with an external multi-row, multi-bank refresh function based on optimized command sequences involves determining, at initialization time of the DRAM, inter-operation timing parameters for the external multi-row, multi-bank refresh function, determining optimized timing parameters for row-level activation (ACT) and pre-charge (PRE) commands, and applying the optimized timing parameters for the row-level ACT and PRE commands for refreshing the DRAM with the external multi-row multi-bank refresh function. The auto-refresh function of an SDRAM is replaced.
