Abstract

We demonstrate the bit functionality of a low-voltage, embedded ferroelectric random-access memory constructed using a 130 nm gate and five-level Cu/FSG interconnect process. By inserting the two additional masks required for the eFRAM module into this logic flow, we have co-integrated ferroelectric memory and SRAM on a single wafer.
在130 nm, 5 LM Cu/FSG逻辑过程中嵌入4mb高密度铁电存储器的演示
我们展示了使用130 nm栅极和五电平Cu/FSG互连工艺构建的低压嵌入式铁电随机存取存储器的位功能。通过将eFRAM模块所需的两个额外掩模插入到该逻辑流中,我们在单个晶圆上实现了铁电存储器和SRAM的协集成。
