We have firstly demonstrated a hybrid flash including both NOR and NAND cell in a single chip using 90 nm logic technology for S-SIM (Super-Subscriber Identity Module) application. The memory sizes are 16 MB NAND and 768 kB NOR flash, respectively. The flash memory cells exhibited over 10 k-cycle endurance and 10-year retention for the successful smart card application.

In this paper, the authors propose an effective method of identifying, online, both stator and rotor resistances, which are useful in the speed control of induction motors without rotational transducers, a scheme which is robust with respect to variations in motor parameters. Their identification method for both stator and rotor resistances uses only information of stator currents and voltages. It can provide fairly good identification accuracy regardless of load conditions. Some experimental results are presented to demonstrate the practical use of this identification method.
