Abstract
A high efficiency N channel single poly OTP (One time programmable memory) cell structure is proposed in this paper. The cell consists of one NMOS transistor and one MOS capacitor. NLDD implant is blocked in the NMOS area of the cell to improve program efficiency and reduce channel length. The NMOS gate and the capacitor top plate is the same polysilicon gate. It is electrical isolated and works as "floating gate". The capacitor bottom plate is the lateral diffusion region of NLDD. It works as the "control gate". In comparing with traditional structure the cell size shrinks 40% and can be easily integrated into a standard CMOS process without additional mask.

Abstract
The Smart domestic protection monitoring gadget has been designed developed, examined and validated. It makes use of the RF (radio frequency) generation to monitor the reputation and security of the electrical device. The gadget has been used to store energy. The clever home is a complex era, on the equal time it is growing, the era that used in this research are Global System for virtual cellular verbal exchange (GSM), Frequency Hopping Method and PIC18F452 Microcontroller. The One Time Password (OTP) concept of clever houses offers reliable, efficient and safe surroundings for occupants. An OTP is applied as the communication tool among the hardware and the software. A GUI is developed and configured which permits the characteristic of generated OTP provider. The auto generated OTP is delivered to the house owners and if he tries to break security then OTP session time out will expire. We can outline Frequency Hopping as a communication scheme among a transmitter and a receiver. Frequency Hopping is the mechanism where in the machine adjustments the frequency (uplink and downlink) at some stage in transmission at normal periods. It allows the RF channel used for signaling channel (SDCCH) time slot or traffic channel (TCH) time slots, to trade frequency each TDMA frame (four. 615 ms). The frequency is modified on an in line with burst basis, because of this that all the bits in a burst are transmitted on the equal frequency.
