Abstract :
A fast self-convergent programming scheme has been developed for MV/analog data storage in floating-gate MOS memories. In the scheme, the built-in feedback mechanism of the channel hot electron injection phenomenon is used for fast and accurate data writing, As a result, 4-bit-resolution writing can be achieved in less than 10 μs without write/verify cycles. In addition, a new dual-transistor memory cell is proposed to enable more accurate analog data writing by real-time monitoring during data writing
