Abstract:
Bit line connections for non-volatile storage devices and methods for fabricating the same are disclosed. At least two different types of bit line connections may be used between memory cells and bit lines. The different types of bit line connections may be structurally different from each other as follows. One type of bit line connection may include a metal pad between an upper via and lower via. Another type of bit line connection may include an upper via and lower via, but does not include the metal pad. Three rows of bit line connections may be used to relax the pitch. For example, two rows of bit line connections on the outside may have the metal pad, whereas bit line connections in the middle row do not have the metal pad.
