Samsung patents faster data lookup using CXL memory chips

Samsung describes a method for storing large data tables, known as embedding tables, directly in the memory of specialized computer chips called CXL-PNM devices. This setup allows the chips to search through different parts of the data at the same time, or in parallel, using their own built-in processing power.

Why it mattersThis could help computers handle massive amounts of data more efficiently, which is useful for tasks like processing large databases or running complex software models.

In the filing’s own words

One or more example embodiments are directed to a storing method of an embedding table, an apparatus, an electronic device, a non-transitory storage medium, and/or a system, the storing method including: acquiring an embedding table; and storing the embedding table in a memory of at least one CXL-PNM device, the storing enabling the at least one CXL-PNM device to perform parallel lookup of the embedding table in the memory using processing circuitry of the at least one CXL-PNM device, wherein the at least one CXL-PNM device includes the memory and the processing circuitry.

What exactly they claim (claim 1)

1. A storing method of an embedding table, the storing method comprising: acquiring an embedding table; storing the embedding table in a memory of at least one Compute Express Link-based Processing-Near-Memory (CXL-PNM) device, wherein each CXL-PNM device of the at least one CXL-PNM device comprises processing circuitry coupled with the memory; and performing parallel lookup of respective portions of the embedding table in the memory, in parallel, using the processing circuitry of the at least one CXL-PNM device.
