Semiconductor device and operation method thereof, system, and electronic device

A system, comprising:

• at least one semiconductor device comprising a memory array and a peripheral circuit coupled to the memory array, the memory array comprising a plurality of memory cells, the peripheral circuit configured to:
• in a first phase, perform a first program operation on a first memory cell coupled to a first word line in a first word line group;
• in a second phase, perform a second program operation on a second memory cell coupled to a second word line in a second word line group to write weight data into the second memory cell;
• and
• in a third phase, perform a third program operation on a third memory cell coupled to a third word line in the first word line group;
• and in the third phase, apply a first read voltage to a fourth word line in a third word line group to obtain a current of a bit line coupled to the third memory cell;
• and
• a controller coupled to the at least one semiconductor device and configured to send input data to the semiconductor device and receive an operation result of the semiconductor device.
