The embedded SRAM is an important block for monolithic TFT-LCD driver IC used for storing image data.To meet the requirement of low-power

this paper presents a 1.8Mb HWD SRAM with dynamic word line decoder.Based on SMIC 0.18μm CMOS process

the designed SRAM is verified by Hspice and Ultrasim.The peak dynamic power dissipation of dynamic word line decoder decreases by 20%than that of static word line decoder.The peak dynamic power dissipation of designed SRAM decreases by 16%than that of DWL SRAM.The simulation results show that the reading and writing time are less than 8ns

dynamic peak power dissipation is less than 123mW and the static power dissipation is 0. 81mW at the operating frequency of 31MHz.
