Samsung patents memory chip using mixed crystal structure

Patent drawing from the official filing.

Samsung has filed a patent for a type of memory called magnetic random access memory (MRAM). The design uses a specific layer made of an alloy containing manganese that has two different crystal structures in different parts of the same layer.

Why it mattersThis is a technical improvement to how data is stored in computer chips, which could lead to faster or more efficient memory in future devices.

In the filing’s own words

A magnetic random access memory (MRAM) is provided. The MRAM includes: a first layer; a second layer; and a first free layer (FL) disposed between the first layer and the second layer, wherein the first FL includes an Mn-based alloy, and wherein a first portion of the first FL adjacent to the first layer or adjacent to the second layer has an fcc-crystal phase, and a second portion of the first FL adjacent to the first layer or adjacent to the second layer has a bcc-crystal phase.

What exactly they claim (claim 1)

1. A magnetic random access memory (MRAM) comprising: a first layer; a second layer; and a first free layer (FL) disposed between the first layer and the second layer, wherein the first FL includes an Mn-based alloy, and wherein a first portion of the first FL adjacent to the first layer or adjacent to the second layer has an fcc-crystal phase, and a second portion of the first FL adjacent to the first layer or adjacent to the second layer has a bcc-crystal phase.
