WebFeb 1, 2015 · Since the invention of flash memory by Dr. Fujio Masuoka in 1981, flash memory is one of the key enablers to realize the modern day’s information technology (IT) products, such as smart phones and mobile computing devices. Typical flash memory devices are Floating Gate (FG) flash memory and nitride based charge trap flash … Webcontrolled learning rate in Charge Trap Flash (CTF) by pulse width modulation of input gate pulse. We further study the effect of cycle to cycle (C2C) and device to device (D2D) variability, and limits of charge fluctuation with scaling on the learning rate. The comparison of CTF as synapse with other state-of-the-art devices is carried out.
