Slow Write Driver Faults in 65nm SRAM Technology: Analysis and March Test Solution

Abstract : This paper presents an analysis of the electrical origins of Slow Write Driver Faults (SWDFs) [1] that may affect SRAM write drivers in 65nm technology. This type of fault is the consequence of resistive-open defects in the control part of the write driver. It involves an erroneous write operation when the same write driver performs two successive write operations with opposite data values. In the first part of the paper, we present the SWDF electrical phenomena and their consequences on the SRAM functioning. Next, we show how SWDFs can be sensitized and observed and how a standard March test is able to detect this type of fault.
