A 32 kb 0.35-1.2 V, 50 MHz-2.5 GHz Bit-Interleaved SRAM With 8 T SRAM Cell and Data Dependent Write Assist in 28-nm UTBB-FDSOI CMOS.

An optimized co-design of SRAM cell, assist schemes, and layout is proposed to achieve wide voltage range operation of SRAM from 0.35-1.2 V at all process corners. A differential read asymmetric 8 T memory cell and a data dependent differential supply and body modulation write assist scheme are proposed. We also propose a layout that reduces metal capacitance of wordlines by 54% and also enables b...
