摘要:
A memory array comprising vertical memory cells does not require any isolation layers between cells. Thus, a very compact, high density memory array can be achieved. Each memory cell in the memory array is configured to store 4 bits of data per cell. Multi level charge techniques can be used to increase the number of bit per cell and achieve further increased density for the memory array.

A method is provided of forming an assisted charge memory (AC-memory) cell. The method uses a two-sided charge trap memory cell that includes a two-sided charge trapping layer. A charge is formed in at least a portion of the two-sided charge trapping layer. One side (AC-side) of the two-sided charge trapping layer always has a fixed high threshold voltage (Vt) level which is the assisted charge for the AC-memory cell. The other side (data-side) is used for memory operations.

A semiconductor process test structure comprises an electrode, a charge-trapping layer, and a diffusion region. The test structure is a capacitor-like structure in which the charge-trapping layer will trap charges during various processing steps. Gate-induced drain leakage (GIDL) measurement techniques can then be used to characterize the charging status of the test structure.

An operating method of a memory array is provided. The operating method includes performing a programming operation. The programming operation is performed by applying a first voltage to a bit line of the memory array and a second voltage to a plurality of word lines of the memory array to cause simultaneously programming a plurality of selected memory cells in the memory array.
