The Spansion 65nm 2Gb MirrorBit ORNAND is an important step for the organization. It continues their commitment to deliver a process lithography shrink every year for the past 3 years.
The first NOR flash from Spansion to use MirrorBit Quad technology – an architecture that stores four-bits-per-cell. MirrorBit Quad doubles the density of MirrorBit with the added ability to store different charge states in each of the two locations.
To achieve a 45nm process node Matsushita has used 193nm immersion lithography, stress-induced mobility-enhanced transistors, low-k dielectrics and design-for-manufacturability technologies.
The 68nm device from Samsung is the smallest process lithography DRAM from Samsung analyzed by Semiconductor Insights to date with a 13.7Mb/mm2 rating.
