Scientists have actually established an innovative stage change memory gadget that assures low power consumption and minimized manufacturing costs. This advancement, potentially replacing DRAM and NAND flash memory, is significant for its effectiveness and could substantially impact the future of memory and neuromorphic computing technology. Credit: SciTechDaily.comKAIST scientists have actually created a low-power, affordable phase change memory gadget, setting a new standard in memory technology.A team of Korean researchers is making headings by establishing a new memory gadget that can be used to change existing memory or used in implementing neuromorphic computing for next-generation expert system hardware for its low processing expenses and ultra-low power consumption.KAIST (President Kwang-Hyung Lee) announced on April 4th that Professor Shinhyun Chois research study team in the School of Electrical Engineering has developed a next-generation stage modification memory * device including ultra-low-power usage that can change DRAM and NAND flash memory.Phase Change MemoryA memory device that shops and/or procedures information by changing the crystalline states of products to be crystalline or amorphous utilizing heat, thereby altering its resistance state.Existing phase change memory has issues such as a costly fabrication process for making extremely scaled devices and requiring a substantial amount of power for operation. To resolve these problems, Professor Chois research group developed an ultra-low power stage modification memory gadget by electrically forming an extremely little nanometer (nm) scale stage adjustable filament without pricey fabrication procedures. This new development has the groundbreaking benefit of not only having an extremely low processing expense but likewise allowing operating with ultra-low power consumption.DRAM, among the most widely utilized memory, is very fast, but has unpredictable qualities in which data vanishes when the power is switched off. NAND flash memory, a storage device, has reasonably sluggish read/write speeds, however it has non-volatile characteristic that allows it to protect the information even when the power is cut off.Figure 1.

For this reason, stage modification memory is being highlighted as the next-generation memory that can change existing memory, and is being actively researched as a memory technology or neuromorphic computing innovation that simulates the human brain.However, conventional stage modification memory devices require a considerable quantity of power to run, making it difficult to make practical large-capacity memory items or realize a neuromorphic computing system. In order to make the most of the thermal effectiveness for memory device operation, previous research study efforts focused on reducing the power consumption by shrinking the physical size of the device through the use of the cutting edge lithography innovations, however they were met with constraints in terms of usefulness as the degree of enhancement in power intake was very little whereas the cost and the trouble of fabrication increased with each improvement.In order to resolve the power intake issue of phase change memory, Professor Shinhyun Chois research group developed a technique to electrically form stage change materials in very small area, effectively implementing an ultra-low-power phase modification memory device that takes in 15 times less power than a conventional stage change memory gadget produced with the expensive lithography tool.Professor Shinhyun Choi revealed strong confidence in how this research study will span out in the future in the brand-new field of research saying, “The phase modification memory gadget we have actually established is substantial as it provides an unique method to fix the remaining issues in producing a memory device at a considerably enhanced manufacturing cost and energy performance. We anticipate the results of our research study to end up being the foundation of future electronic engineering, enabling various applications consisting of high-density three-dimensional vertical memory and neuromorphic computing systems as it opened the possibilities to pick from a variety of products.” He went on to include, “I would like to thank the National Research Foundation of Korea and the National NanoFab Center for supporting this research. “This research study, in which See-On Park, a trainee of MS-PhD Integrated Program, and Seokman Hong, a doctoral trainee of the School of Electrical Engineering at KAIST, took part as very first authors, was released on April 4 in the April concern of the popular global academic journal Nature.Reference: “Phase-change memory via a phase-changeable self-confined nano-filament” by See-On Park, Seokman Hong, Su-Jin Sung, Dawon Kim, Seokho Seo, Hakcheon Jeong, Taehoon Park, Won Joon Cho, Jeehwan Kim and Shinhyun Choi, 3 April 2024, Nature.DOI: 10.1038/ s41586-024-07230-5This research study was conducted with assistance from the Next-Generation Intelligent Semiconductor Technology Development Project, PIM AI Semiconductor Core Technology Development (Device) Project, Excellent Emerging Research Program of the National Research Foundation of Korea, and the Semiconductor Process-based Nanomedical Devices Development Project of the National NanoFab.
