Samsung patents memory trick to fetch data before you ask
Samsung has been granted a patent for a method that helps computer memory fetch data faster. The system looks up a data request twice in a queue, moving it to a new position between checks to prepare the data for immediate use.
In the filing’s own words
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.
What exactly they claim (claim 1)
1. 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.
