Tosh, SanDisk To Make 3D Chips
BiCS is said to improve density and significantly reduce the overall size of the chip. It uses a “charge trap” that is claimed to stop electrons leaking between layers, improving reliability of the product.
The technology creates a 3D checkerboard where memory cells sit at the intersection of word lines and bit lines, allowing the cells to be addressed individually.
All this means that the data can be written and read in small sizes, hopefully leading to faster and more efficient read/write processes.
