What is Word line?
The wire connected to the gates of memory-cell transistors that selects the row to read or write.
Field: DRAM
Word line in the explanations
Buried-channel array transistors (BCAT) became mainstream around 2010 and also reduce capacitance between the word line and overlying wiring.
What is the main purpose of burying the gate electrode in a…In the cell array, a word line selects a row and turns on all its cell transistors at once, and bit lines carry charge to and from the capacitors, ending at sense amplifiers.
In a DRAM cell array, which line connects to the gates of t…But each word line contacts cells on only one bit line of the pair, so the cell area is 8F².
In DRAM cell arrays, which bit-line arrangement places the …
