Claim 0:
1. A memory device for in-memory search, the memory device comprises a plurality of memory cells, each of the memory cells stores a stored data and receives a search data, each of the memory cells comprising:
a first transistor, having a first threshold voltage and receiving a first gate bias; and
a second transistor, connected to the first transistor, the second transistor has a second threshold voltage and receives a second gate bias;
wherein, the stored data is encoded according to the first threshold voltage and the second threshold voltage, the search data is encoded according to the first gate bias and the second gate bias, there is a mismatch distance between the stored data and the search data, and an output current generated by each of the memory cells is related to the mismatch distance.
