Abstract :
This paper describes the design and results of SRAM experiments from a prototype test chip in IBM´s .18 μm 7 level metal copper technology. Results and approaches for assuring product applications at 1 GHz across wide process ranges will be discussed. Aggressive product cycle time SRAM applications for IBM´s S/390 L2 cache chips require multifaceted approaches to address the following: (a) SRAM operability in product-like clocking and ABIST environments, (b) Demonstration of yield using 2 dimensional redundancy, (c) Characterization of SRAM signals used in the macro timing rules, (d) Obtain high volume pre-product manufacturing test data, (e) Verify SRAM functionality at technology stress test conditions
