Abstract
A method and apparatus are provided for performing early prefetch in a memory system. A method includes receiving a data request including an address of a data page stored in a memory device; storing the data request at a first position in a request queue; accessing the data request stored at the first position and performing a first lookup operation for the data request; updating the device request queue, which includes moving the data request stored at the first position to a second position in the request queue; and accessing the data request stored at the second position and performing a second lookup operation for the data request.
Claims22
A method for performing early prefetch in a memory system, the method comprising:
- receiving a data request including an address of a data page stored in a memory device;
- storing the data request at a first position in a request queue;
- accessing the data request stored at the first position and performing a first lookup operation for the data request;
- updating the request queue, which includes moving the data request stored at the first position to a second position in the request queue;
- and
- accessing the data request stored at the second position and performing a second lookup operation for the data request.
A memory system, comprising:
- a memory device;
- a request queue;
- and
- a processor configured to:
- receive a data request including an address of a data page stored in the memory device,
- store the data request at a first position in the request queue,
- access the data request stored at the first position and perform a first lookup operation for the data request,
- update the request queue, which includes moving the data request stored at the first position to a second position in the request queue, and
- access the data request stored at the second position and perform a second lookup operation for the data request.
