Abstract :
In this paper a highly flexible low power single port Static Random Access Memory (SRAM) compiler design is presented. The Divided Word Line (DWL) and Divided Bit Line (DBL) scheme were implemented for reducing active power. Particular emphasis was put to decrease standby power consumption in word line driver. The forced-stack devices as pulse generation element was introduced for sensing enable. This guarantees SRAM can work in low voltage without losing design margin. A test-chip with 17 embedded SRAMs has been fabricated in UMC 90-nm low leakage CMOS logic process.
