Samsung patents new way to manage NAND memory space

Patent drawing
Patent drawing from the official filing.

Samsung has filed a patent for a system that manages NAND flash memory by creating separate translation layers for different sections of the storage. The method uses a list of available space to assign these sections and tracks them in an allocation list.

Why it mattersThis is a routine improvement to how storage controllers organize data, which helps ensure memory chips work efficiently and reliably.

In the filing’s own words

Provided are systems, methods, and apparatuses for byte-addressable NAND memory. In one or more examples, the systems, devices, and methods include generating a first flash translation layer for a first allocation of a memory device; generating a second flash translation layer for a second allocation of the memory device, the first allocation and the second allocation being based on a pool of allocation space indicated in a freelist; and adding at least one of the first allocation or the second allocation to an allocation list based on generating at least one of the first flash translation layer or the second flash translation layer.

What exactly they claim (claim 1)

1. A method comprising: generating a first flash translation layer for a first allocation of a memory device; generating a second flash translation layer for a second allocation of the memory device, the first allocation and the second allocation being based on a pool of allocation space indicated in a freelist; and adding at least one of the first allocation or the second allocation to an allocation list based on generating at least one of the first flash translation layer or the second flash translation layer.
