Subject:128bit eFuse OTP IP design
Problem statement: creating a convenable circuit that satisfied these specifications
– Supply voltage: VDD=2.2V – VIO=5.5VTemperature:-40C 25 C to 125C
Operating Mode :Program/Program Verify-Read/Read Program.
–Program Verify Read:10k (PVR Mode)
– Read Mode :5k {Read_Programmed Cell& Read_Uprogrammed Cell
– Current :<100uA. (Decreasing current from 168.4uA to 100uA
– checking the sensing resistance and read current
About Sensing resistance : Lower than 10K(PVR Mode), Lower than 5K(Read Mode), at all corner simulation
About Read Current: Lower than 100uA at all corner
original circuits (Block diagram) read current maximum value is 168.4uA, its over limitation
creating a convenable circuit (Block diagram) that make the current smaller than 100uA.
Expected result: Suitable block diagram have to be find out by modifying the above simulation circuits based on the requirements.
