This paper provides statistical analysis on real data taken from state-of-the-art MLC NAND flash memory cells. The analysis allows separation of different sources affecting the output values of the cell. Interference due to floating gate coupling is isolated. The effect of noise and interference on the victim cell after repeated program/erase cycles as well as baking is investigated.
Lower cost per bit and higher density NAND flash memory is a general trend in nonvolatile memory applications, such as MP3 players, digital still cameras, video camcorders, USB memories and solid-state disk. Technology scaling has become expected from consumers and recently higher number of bits per cell, such as 8-level cell or 16-level cell, is becoming a viable alternative solution due to difficulties...
Glomus tumors can be classified into solitary and multiple glomus tumors. Congenital multiple glomus tumors are extremely rare, and only 12 cases have been reported in the world literature. We describe the first case with giant congenital multiple patch-like glomus tumors that show partial atrophy. (J Am Acad Dermatol 1999;40:826-8.)
