Abstract :
A fast-access intermediate supply voltage level BiCMOS SRAM (ISVOL) architecture is proposed for advancing circuit technology to megabit-level SRAMs using low-submicron MOSFETs. To verify this concept´s effectiveness, a 256-kb SRAM, with a typical access time of 5 ns, is evaluated and reported. The access time dependence of the supply voltage is shown. This architecture can suppress the access time variance to within 4% for a 15% supply voltage variation
