Low Cost ‘On Pitch Select Gate’ (OPS) Technology for 3D Flash Memory

Amrit Prakash, Xiaochen Zhu, Guirong Liang, Masaaki Higashitani et autres

Contrary to the general perception of 3D flash memory technology nodes being defined by the vertical stacking of word line layers, we, for the first time, present an unconventional approach employed in the mass production of BiCS FLASH™ generation 8 3D flash …

Disturbless flash memory due to high boost efficiency on BiCS structure and optimal memory film stack for ultra high density storage device

Yosuke Komori, M. Kido, Masaru Kito, Ryota Katsumata et autres

Program and erase operation on NAND-string of Bit-Cost Scalable (BiCS) flash memory has been successfully achieved. High boost efficiency of floating pillars and ONON (block oxide/charge SiN/tunnel oxide/tunnel SiN) structure as a memory film stack improve disturbance characteristics enough to realize tera-bit …

Pipe-shaped BiCS flash memory with 16 stacked layers and multi-level-cell operation for ultra high density storage devices

Ryota Katsumata, Masaru Kito, Yoshiaki Fukuzumi, M. Kido et autres

We propose pipe-shaped bit cost scalable (P-BiCS) flash memory which consists of pipe-shaped NAND strings folded like a u-shape instead of the straight-shape. P-BiCS flash technology achieves a highly reliable memory film of which the program and erase (P/E) operation is managed …
