Abstract
A memory device for providing hotness tracking and a method operating the memory device are provided. The device includes a memory array including a memory space, a controller configured to set focus address ranges in the memory space based on a focus request from a host for hotness tracking, and one or more counters including a counter configured to count memory accesses to a corresponding focus address range among the one or more focus address ranges to determine a counted value, and provide the counted value to the host.
Claims20
A memory device comprising:
- a memory array comprising a memory space;
- a controller configured to set focus address ranges in the memory space based on a focus request from a host for hotness tracking;
- and
- one or more counters, comprising a counter configured to count memory accesses to a corresponding focus address range among the focus address ranges to generate a counted value, and provide the counted value to the host.
An electronic device comprising:
- a host;
- a first-tier memory device comprising a first memory space;
- and
- a second-tier memory device comprising a second memory space and having a slower processing speed than the first-tier memory device,
- wherein the second-tier memory device is configured to:
- set focus address ranges in the second memory space based on a focus request from the host for hotness tracking;
- count memory accesses to a corresponding focus address range among the focus address ranges to determine a counted value of a counter;
- and
- provide the counted value to the host.
A method of operating a memory device, the method comprising:
- setting one or more focus address ranges in a memory space based on a focus request from a host for hotness tracking;
- counting memory accesses to a corresponding focus address range using a counter to determine a counted value of a counter;
- and
- providing the counted value to the host.
