Abstract
A refresh of a DRAM having at least a fast and a slow refresh rate includes encoding a pointer on a row or rows with refresh information, reading the refresh information, and incrementing a fast refresh address counter with the refresh information. The refresh may be performed by encoding one or more cells on a row that may require a fast refresh, one or more cells on a group of rows that may require a fast refresh, or one or more cells on a row that may not require a fast refresh.
