A new operation strategy has been proposed to reduce the programming voltage in RESET operation of phase change memory (PCM). The amorphous state generated after first pulse would restrict the current flowing through the phase change materials, increasing the heat efficiency. Thus, the amorphous state in the second pulse would increase. The accumulative amorphous state would cover the bottom electrode...
The electronic industry is moving toward smaller, faster, and cheaper. In the case of CSP or BGA, the components are reducing in pitch and ball size but increasing in package size. Due to the high complexity in design, many components inevitably suffer from warpage at soldering temperature, and consequently result in head-in-pillow (HIP) defect. The symptom of this defect is that the solder ball on...
This paper describes an optimized hardware and software design for the heat meter. It is equipped with the international popular low-power consumption single-chip microcontroller MSP430FW425, temperature sensor Pt1000, impeller flow meter and zero energy-consuming magnetic sensor. They improve the precision and sensitivity of heat measurement. It also concludes the RFID module which has realized the...
