Failure analysis of SRAM memory requires the understanding of the components of cell, the operation of SRAM, layout, testing and the electrical signature of the fails. An overview of all the above aspects will be provided as an introduction. The methodology of failure analysis of SRAM is described showing the interaction of SRAM testing, electrical failure signature and the probable cause of fail, which can lead to physical failure analysis.
