Smartphones and solid-state drives use VNAND structures to store data, while pictures are made up of pixels represented by combinations of 3 numbers in binary. Memory cells in these devices can hold multiple levels of electrons, allowing for efficient storage of information.
Insights
- VNAND structures in smartphones and solid-state drives use charge trap flash memory cells to store data, with each cell capable of holding 3 bits of information due to 8 electron levels, organized in vertical strings and pages within memory chips.
- Images captured by a 12-megapixel camera translate to 293 million bits of data, with each pixel requiring 24 bits to define its color through combinations of red, green, and blue values, showcasing the intricate binary-based storage and representation of visual information.
