This is a surface potential image of a static random access memory (SRAM) with a scanning range of 15 μm. SRAM is a high-speed memory technology mainly used as cache for high-performance processor chips. Characterization of the surface potential of SRAM can provide a powerful reference for the processing and manufacturing of high-performance processor chips.
