Control of refresh operation for first memory region at first frequency and for second memory region at second frequency
An apparatus comprises first and second memory regions each to store data using a data storage technology for which retention of data for longer than a predetermined period of time is dependent on a refresh operation for refreshing data in the memory region being performed at a frequency that is greater than or equal to a minimum refresh frequency. The apparatus further comprises at least one controller to control storage of data in the first memory region with the refresh operation performed at a first frequency lower than said minimum refresh frequency when valid data is stored in the first memory region, and to control storage of data in the second memory region with the refresh operation performed at a second frequency that is greater than or equal to said minimum refresh frequency. The at least one controller is configured to communicate with the first memory region via a first memory channel and with the second memory region via a second memory channel.
