APPARATUS FOR EVICTING COLD DATA FROM VOLATILE MEMORY DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 17970103 titled 'APPARATUS FOR EVICTING COLD DATA FROM VOLATILE MEMORY DEVICE

Simplified Explanation

The patent application describes a memory system that includes a non-volatile memory device, a volatile memory device, and a controller.

  • The memory system is designed to store and manage data efficiently.
  • The non-volatile memory device is used to store data that does not need to be accessed frequently.
  • The volatile memory device is used to store data that needs to be accessed frequently.
  • The volatile memory device performs a refresh operation on data stored in a word line multiple times, and then evicts the less frequently accessed data.
  • The controller controls the operations of both the volatile and non-volatile memory devices.
  • The controller is responsible for storing the evicted data into the non-volatile memory device.
  • This memory system aims to optimize the usage of memory resources and improve overall system performance.


Original Abstract Submitted

A memory system may include: a non-volatile memory device, a volatile memory device suitable for defining, as cold data, data stored in a word line, on which a refresh operation is performed a number of times greater than a reference number among a plurality of word lines coupled to a volatile memory cell array, and evicting the cold data, and a controller suitable for controlling operations of the volatile memory device and the non-volatile memory device, and storing the evicted cold data into the non-volatile memory device.
