Memory chip's protection circuit and memory

The utility model discloses a memory chip's protection circuit and memory is applicable to circuit technical field. The memory chip's that this practical embodiment provided protection circuit, it is continuous with memory chip's power input end, include: switch element, sampling unit and comparing element, when the wrong power of memory chip's power input termination, sampling unit carries out current sample to memory chip's power input end to according to sample current formation sample voltage, comparing element receives sample voltage, the reference voltage of comparing element through comparing the output of sample voltage and power supply, and then export control signal to the switch element, turn -off with the control switch unit. Realized when memory chip meets wrong power supply, can cut off route and then protection memory chip between power supply and the memory chip, greatly reduced the risk that is burnt out of lighting control system memory chip. 本实用新型公开了种存储芯片的保护电路及存储器，适用于电路技术领域。本实用实施例提供的种存储芯片的保
