Understanding MRAM Principles and Technology
MRAM: non-volatile memory with SRAM-like speed, DRAM density and virtually unlimited endurance using magnetic tunnel junctions.
MRAM: non-volatile memory with SRAM-like speed, DRAM density and virtually unlimited endurance using magnetic tunnel junctions.
Explains DDR5 subchannels: splitting 64-bit DIMMs into two 32-bit subchannels so BL=16 yields 64-byte transfers matching CPU cache lines.
Channel hole formation and high-aspect-ratio etching for stacked memory: amorphous carbon mask, ICP/CCP RIE, control of diameter, sidewalls and depth.
3D NAND fabrication: substrate prep, stacked oxide/nitride layers, channel via & slit etch, TiN/W fill, polysilicon channels and metal bitlines
