| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | An energy-efficient and high-throughput HZO FeFET Computation-in-Memory (CiM) is proposed. The FeFET CiM performs voltage-sensing multiply-accumulate (MAC) operation using source-follower read locally to multiply the input of neural network and weights stored in FeFETs, and charge-sharing globally to sum the multiplied values in the bit-line direction. The proposed FeFET CiM is not affected by read-disturb and achieves 3 bit/cell operation after 10 years of data-retention. The FeFET CiM achieves high-throughput 66 TOPS/W, which is 64 times higher than the conventional current-sensing CiM. | |
