Content
"Source side" refers to the end of a NAND string or side of a three-dimensional memory array connected to the source layer or line on a memory die. The term comes from the source terminal of a field effect transistor or similar component. In a daisy-chained string of transistors, the source terminal of the first transistor may be connected to a source line, a ground or some other lower voltage line, and the drain terminal may be connected to the source terminal of the next transistor, that transistor's drain terminal may be connected to the next source terminal and so on, with the drain terminal of the final transistor connected to a higher voltage signal or power line. The gate terminal of each transistor may then control whether or not current flows through the transistor from source to drain, and through the string from source line to bit line.
