Abstract :
A novel low power dual-port CMOS SRAM structure is described. The inherent low power advantage is obtained by using current-mode rather than voltage-mode signal transmission. The design of this new dual-port memory cell and current-mode sense amplifier is based on 0.5 μm, 5 V CMOS logic process technology. HSPICE simulations show that the circuits can operate at high speed even if the supply voltage is reduced to 2 V. The dual-port memory cell is most suitable for the design of FIFO buffers
