WebThe figure-2 depicts architecture of NOR flash memory. As shown, one end of cell is interfaced to source line and other end to bit line. This resembles NOR gate. Advantages : It offers enough address lines useful to map complete memory range. It provides faster random read speed. Web12 de fev. de 2024 · As suspected it was 1 bit error. Correct reading happened with supply >3.55V (3.3V part) and temperature >60 deg C (together). Also tried to couple some RF noise to the die, but that was unsuccessful idea. I was very surprised, because the correct bit was "1" which somehow degraded to "0". That is opposite from what would be expected.
