Filed: 2019-06-13
Abstract: Various embodiments of the present invention relate to an integrated memory chip including a memory array having a strap-cell architecture, which is capable of reducing strap-line density while reducing the number of different strap-cell types. According to some of the embodiments, a memory array is limited to three different types of a strap cell, which are a source line/erasure gate (SLEG) strap cell, a control gate/word line (CGWL) strap cell, and a word line strap cell. If the number of different strap-cell types is small, the design of the memory array can be simplified and the design of a corresponding interconnect structure can be more simplified. Moreover, in some of the embodiments, the three different strap-cell types, for example, can electrically combine a word line, an erasure gate and a control gate with a corresponding strap line in different metallization layers of an interconnect structure. As strap lines are spread between the different metallization layers, strap-line density is reduced.
