Chip storage data principle:
1, the unit in sram is a number of switches to form a trigger, which can stably store 0, 1 signals, and can change the stored value through timing and input signals.
2, dram, mainly according to the power on the capacitor, when the power is large, the high voltage means 1, and conversely, the 0 chip is composed of a large number of these units, so it can store data.
