Title:
PHASE-CHANGE STORAGE MATERIAL AND PREPARATION METHOD THEREFOR, PHASE-CHANGE STORAGE CHIP AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/193754
Kind Code:
A1
Abstract:
The present invention relates to the technical field of data storage, in particular to a phase-change storage material and a preparation method therefor, a phase-change storage chip and a device. The phase-change storage material comprises a material represented by TiaSbbTecDd, wherein a represents the atom percent of Ti, b represents the atom percent of Sb, c represents the atom percent of Te, d represents the atom percent of element D, a+b+c+d=1, 3%≤a≤45%, and 0.5≤(b:c)≤3; and D is a doping element, and 0≤d≤15%. The phase-change storage material has relatively low operation power consumption and operation time delay.
