Samsung patents data prefetching to speed up memory access

Patent drawing from the official filing.

Samsung describes a method where a computer chip predicts the next piece of data a program needs by spotting patterns in previous requests. It then moves that data from slower main memory to faster cache memory in advance, using different data sizes for each storage layer to improve efficiency.

Why it mattersThis is a standard technique to make processors run faster by reducing wait times, which can lead to slightly better performance in everyday tasks like opening apps or loading files.

In the filing’s own words

A system and method for prefetching data. In some embodiments, a method includes: receiving a first read command, the first read command including a first address; receiving a second read command, the second read command including a second address; determining, based on the first address and the second address, that the second read command is a command of a sequence having a first stride; and based on determining that the second read command is a command of a sequence having a first stride, prefetching a first data unit from a first memory to a second memory, the first memory having a first read granularity, and the second memory having a second read granularity, different from the first read granularity.

What exactly they claim (claim 1)

1. A method, comprising: receiving a first read command, the first read command including a first address; receiving a second read command, the second read command including a second address; determining, based on the first address and the second address, that the second read command is a command of a sequence having a first stride; and based on determining that the second read command is a command of a sequence having a first stride, prefetching a first data unit from a first memory to a second memory, the first memory having a first read granularity, and the second memory having a second read granularity, different from the first read granularity.
