Abstract:
The present disclosure includes apparatuses and methods for vertical access line in a folded digitline sense amplifier. An example apparatus includes an array of memory cells. The memory cells form active areas having adjacent access devices, each access device having a first source/drain region and a second source/drain region separated by a channel region and a gate opposing the channel region. A pair of adjacent memory cells can share a digitline contact at the second source/drain region. A storage node contact can be coupled to respective first source/drain regions and each gate can be connected to vertically oriented access lines formed on opposing side of a depletion region to each access device. An insulator material can be patterned between adjacent digitlines to isolate adjacent memory cells.
