The invention belongs to the field of artificial intelligence hardware acceleration, and discloses a high-density single-fingered eDRAM storage and calculation integrated macro with bit-level sparse perception and kernel-level weight update, which comprises an input buffer, a weight buffer, a word line decoder, a bit line driver, a single-fingered eDRAM array and an output buffer, the weight buffer is used for writing weights from the off-chip and writing the weights into the single-finger eDRAM array line by line, and each single-finger eDRAM storage unit only stores one bit; the input buffer is used for writing an input activation value and transmitting a multi-bit input activation value into the single-fingered eDRAM array bit by bit from a low bit to a high bit, each row of single-fingered eDRAM is equipped with a bit saliency perception analog-to-digital converter BSA-ADC and is used for executing matrix vector multiplication and transmitting a calculation result to a calculation line CL, the BSA-ADC digitalizes an accumulation result on the calculation line, and the calculation line CL is connected with the input buffer. The result is transmitted to the output buffer; the output buffer is used for outputting the calculation result. The integrated macro has the advantages of high density, low energy consumption and high throughput.

The invention discloses a transistor, a semiconductor device, a preparation method thereof and electronic equipment. The transistor comprises a source electrode, a channel region and a drain electrode which are sequentially arranged along a first direction, and a grid electrode which is arranged at the periphery of the channel region in an insulating manner; the source electrode comprises a first semiconductor layer and a second semiconductor layer, the same ends of the first semiconductor layer and the second semiconductor layer in the first direction are connected with the channel region, and the second semiconductor layer is located on the side, close to the grid electrode, of the first semiconductor layer in the direction perpendicular to the first direction. The doping concentration of the first semiconductor layer is smaller than that of the second semiconductor layer. The invention relates to the technical field of semiconductor devices, in particular to a transistor, a semiconductor device, a preparation method of the semiconductor device and electronic equipment, and aims to restrain accumulation of holes in a channel as a starting point, relieve formation of a parasitic bipolar transistor and prolong storage retention time.
