Both NOR and NAND Embedded Hybrid Flash for S-SIM Application Using 90 nm Process Technology

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.
