Storage device, storage equipment and electronic equipment

The embodiment of the invention discloses a storage device, storage equipment and electronic equipment, relates to the technical field of storage, and solves the problems of relatively coarse adjustment granularity, complex circuit design and relatively high cost when the power consumption of an SRAM (Static Random Access Memory) is optimized and reduced in the prior art. According to the specific scheme, the storage device comprises a storage array, a voltage adjusting circuit and a gear adjusting circuit. The storage array comprises a plurality of first storage units and a plurality of second storage units, the resistance values of the first storage units are all larger than those of the second storage units, and the first storage units are used for ensuring that data stored in the second storage units are correctly read. The gear adjusting circuit is used for acquiring first test data from the plurality of first storage units and selecting one of the plurality of gear output ends to output a gear selection
