Abstract
A memory system and an electronic system including the same are provided. The memory system includes a memory device configured to receive data, and a hot page logic configured to receive an address for the data, determine that the address is for a hot page based on an input frequency and an input order of the address, and create hot page information including the address that was determined as associated with the hot page such that a page migration operation of the data is performed.
Claims20
A memory system, comprising:
- a memory device configured to receive data;
- and
- a hot page logic configured to receive an address for the data, configured to determine that the address is for a hot page based on an input frequency and an input order of the address, and configured to create hot page information including the address that was determined as associated with the hot page such that a page migration operation of the data is performed.
An electronic system, comprising:
- a processor configured to output data and an address of the data;
- a first memory system including a first memory device configured to receive the data and a hot page logic configured to receive the address and configured to output hot page information based on an input frequency and an input order of the address;
- and
- a second memory system including a second memory device different from the first memory device,
- wherein a page migration operation for the data is performed based on the hot page information.
A method of operating an electronic system, comprising:
- collecting frequency data and recency data of an address in a first memory system based on an input frequency and an input order of the address for a first data that is input to the first memory system;
- measuring a first data bandwidth of the first data and a second data bandwidth of a second data that is input to a second memory system different from the first memory system;
- performing a calculation operation on the frequency data and the recency data in response to a ratio of the first data bandwidth and the second data bandwidth;
- creating hot page information indicating whether the address is a hot page based on the calculation operation;
- and
- migrating a page for the first data based on the hot page information.
