MONOS Memory Gate Width Optimization for Rewriting

The patent applies local quality by dividing the memory into two distinct regions: a first memory region with a first gate width optimized for program data storage, and a second memory region with a second gate width optimized for processed data storage. Each region has different gate width characteristics tailored to its specific functional requirements, allowing the first region to maintain smaller cell size while the second region provides enhanced driving current for frequent rewriting operations.

The patent segments the memory system into two distinct memory regions: a first memory region for storing program data and a second memory region for storing processed data. This segmentation allows each region to be optimized independently - the first region can use narrower gates suitable for program storage, while the second region uses wider gates that provide higher driving current and withstand frequent rewriting operations, thereby increasing the overall number of rewriting cycles.

The patent implements local quality by creating spatially differentiated gate widths across the memory structure. The first gate width is optimized for program data with smaller area requirements, while the second gate width is optimized for processed data with larger area but higher rewriting capacity. This local differentiation allows the memory to achieve high degree of integration overall while providing enhanced rewriting capacity where needed.
