Summary: 
We analyze the substrate corrent of submicron transistors in the memory cell of ULSI SRAMs in the cases of PMOS and NMOS bit line loads. The lifetime of the transistors is also estimated. The SRAM using an NMOS bit load is found to be better as a hot carrier than that with a PMOS bit load.
