Abstract
Methods of managing data of a storage device responsive to temperature can include measuring a temperature of the storage device, changing a duration of a refresh interval of the buffer memory responsive to the measured temperatures, changing a number of refresh bursts during the refresh interval responsive to the measured temperature, and refreshing data of the buffer memory based on the refresh interval and the number of the refresh bursts that are changed responsive to temperature.
Claims20
A method of managing data of a storage device comprising a buffer memory, the method comprising:
- measuring a temperature of the storage device;
- changing a duration of a refresh interval of the buffer memory responsive to the measured temperature;
- changing a number of refresh bursts during the refresh interval responsive to the measured temperature;
- and
- refreshing data of the buffer memory based on the refresh interval and the number of the refresh bursts that are changed responsive to temperature.
A storage device comprising:
- a data storage unit;
- and
- a controller configured to control the data storage unit, wherein
- the controller comprises:
- a buffer memory configured to temporarily store data transmitted to and/or from the data storage unit;
- and
- a buffer memory controller configured to change a duration of a refresh interval and a number of refresh bursts during the refresh interval responsive to a temperature.
A memory controller comprising:
- a buffer memory control interface configured to control a refresh operation of a buffer memory;
- and
- a temperature interface configured to receive a temperature measurement,
- wherein the memory controller is configured to control the refresh operations of the buffer memory via the buffer memory control interface responsive to the temperature measurement received via the temperature interface.
