Jan Otterstedt (Infineon Technologies, D)


We discuss design aspects of an embedded RRAM macro in a 28nm advanced logic foundry process employed for consumer and industrial products and we present high statistic reliability data of the embedded RRAM coming from test devices and first products to demonstrate the matureness und usability of the embedded emerging memory. We compare failure modes and counter measures with embedded flash from the previous generations. Overall, the 28nm-embedded RRAM is an adequate and available successor of embedded flash from previous generations.
