NROM (TM) - a new non-volatile memory technology: from device to products

NROM (TM) - a new NVM technology has recently been introduced, enabling thr ee major improvements relative to the floating gate technology: one technol ogy for all NVM products (Flash, EEPROM, ROM and Embedded), higher density (2.5F(2) per bit in flash) and simple process with reduced number of masks without any exotic materials. The NROM (TM) cell is based on localized char ge trapping above the junction edge, enabling physically separated two bits per cell. Performance of new NVM NROM (TM) based products show endurance u p to 100 K with retention of 10 years at 150 degreesC. (C) 2001 Elsevier Sc ience B.V. All rights reserved.
