In this letter, a channel-stacked array with tied bit-line (BL) and ground select transistor (GST) is proposed to access each layer independently without additional string select transistors (SSTs) to a conventional planar NAND array. The proposed st

In this letter, we propose a layer selection method by permutations (LSMPs) of string select line (SSL) bias and string select transistor with multi-level states. Due to the increased number of threshold voltage orderings by the permutation, the numb
