1. Multi-bit (4bit, 5bit, 6bit) 3D NAND Flash memory device and process

We develop multi-level (4bit, 5bit, 6bit) technology of 3D NAND Flash memory device and process using new materials and novel process scheme.


2. Stackable DRAM Cell device (3D, 4D, 4F2 stucture)  

We develop stackable DRAM cell device using innovative material, structure, and novel process scheme to break the existing scaling limit of DRAM.


3. Novel device-based neuromorphic computing for AI  

We develop novel device (memristor, charge trap memory) for neuromorphic computing using nanoscale phtolithography process and advanced electron microscopy methods. Our major research articles are as follows:


4. Low-dimensional materials-based nonvolatile memory  

We develop low-dimensional materials-based nonvolatile memory for next-generation flexible nonvolatile memory. Our major research articles are as follows:


5. Novel processing-in-memory circuit  

We develop zero-static power nonvolatile processing-in-memory circuit to overcome von-Nuemann bottleneck.  This  research is related to the Processing-in-Memory (PIM) technology.
Our major research articles are as follows:


6. MRAM (Magnetic Random Access Memory) 

We develop spintronic devices which make use of spin property of electrons. This spin property enables non-volatility and new logic functions. This new device present an important milestone to develop  new type of computing systems that 
This work will be in collaboration with KIST.
